70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)
72 PCB Antenna
The PCB antenna is fabricated on the top copper layerand covered in solder mask The layers below theantenna do not have copper trace It is recommendedthat the module is mounted on the edge of the hostPCB It is permitted for PCB material to be below theantenna structure of the module as long as no coppertraces or planes are on the host PCB in that area

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)
72 PCB Antenna
The PCB antenna is fabricated on the top copper layerand covered in solder mask The layers below theantenna do not have copper trace It is recommendedthat the module is mounted on the edge of the hostPCB It is permitted for PCB material to be below theantenna structure of the module as long as no coppertraces or planes are on the host PCB in that area

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)
72 PCB Antenna
The PCB antenna is fabricated on the top copper layerand covered in solder mask The layers below theantenna do not have copper trace It is recommendedthat the module is mounted on the edge of the hostPCB It is permitted for PCB material to be below theantenna structure of the module as long as no coppertraces or planes are on the host PCB in that area

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)

70 SUPPORTED SERVICES
The RN4020 firmware support the following built-in pro-files listed in Table 7-1 below The services are enabledvia Command API and serviced in the same mannerEach service manages ldquoCharacteristicsrdquo which as datavalues are declared and defined by Bluetooth The val-ues for each characteristic are cached in modulesmemory and can be read by another Bluetooth devicesuch as Smartphone acting in Central role The valuesof every Characteristic are updated via Command APIover UART
71 Public and Private Services
The RN4020 provided the ability to create customerservices If the services are supported on both endpoints of a Bluetooth Low Energy connection such asCentral and Peripheral devices data can beexchanged For example two RN4020 modules candefine a custom (private) service with its own uniquecharacteristics Data can be exchanged easily viaCommand API
Private services are not registered with the BluetoothSIG and therefore not interoperable with other Blue-tooth Low Energy devices unless the device imple-ments the private service An example of a built-inprivate service is Microchip Streaming Data service
For an example on how to create a custom serviceusing the RN4020 refer to ldquoRN4020 Bluetooth LowEnergy Module Userrsquos Guiderdquo (DS70005191)
72 PCB Antenna
The PCB antenna is fabricated on the top copper layerand covered in solder mask The layers below theantenna do not have copper trace It is recommendedthat the module is mounted on the edge of the hostPCB It is permitted for PCB material to be below theantenna structure of the module as long as no coppertraces or planes are on the host PCB in that area
