3 POWER SUPPLY The EVB power can be provided by USB hosts or an external 5V supply which is then converted by LDOs to create the 3.3V and 1.8V needed for the onboard circuits. There is no switch needed for selecting a particular supply. Instead, diodes are installed to provide reverse current protection for each individual supply. Jumpers CN11 may be used to measure the current consumption of the module as described in Section 9. A block diagram of the power supply connections is shown below.

Figure 5 Power supply block diagram

3.1 USB power supply

In the default configuration, the EVB is connected to a PC through at least one of the two mini-USB ports CN13 and CN14. These connections provide the USB-UART serial interfaces and serve as the power sources for the EVB. The mini-USB connector locations are as shown below in Figure 6.

Figure 6 USB connectors location



3.2 External 5V supply

The EVB can also be powered by applying 5V to the Ext_Vin pin of the Arduino interface. This is pin 8 on the CN3 header which is located on the bottom side of the EVB as shown in Figure 7.

Figure 7 Ext_Vin pin location on bottom side of EVB

4 SERIAL INTERFACES The EVB exports 3 module UART ports through either the USB-UART mini-USB connectors or the Arduino header. A block diagram for this is shown in Figure 8.

Figure 8 Exported UART interfaces

In the default configuration, USB ports CN13 (UART A & C) and CN14 (UART B) are connected to a PC for application testing and development; the Arduino interface is not used. The host control for the modem is accomplished through the UART B (CN14) interface. There are two possible options:

• Use a PC application (e.g., PuTTY): connect a mini-USB cable to CN14 and disconnect the Arduino interface. See Section 0 for more instructions.

• Use the Arduino interface (e.g., Nucleo 64 board): connect MCU to the Arduino interface and disconnect the mini-USB cable from CN14. See Section 6.1 for the detailed Arduino interface pin assignments.

UART A & C (CN13) are used for CLI and debugging. See Sections 7.4 for more details.

5 INDICATION AND SERVICES

5.1 Optical Indicators

The EVB has 3 LEDs which serve as status indicators. Their locations on the EVB are shown below.

Figure 9 LED locations on EVB

5.1.1 LED1: PMU_EXT_ALARM status

LED1 shows the power save mode status of the module. It is on whenever the module is not in one of the low power sleep states.

5.1.2 LED2: PWM3 status

LED2 is the status of the PWM3 pin.

5.1.3 LED3: SMA / ANT select status

LED3 indicates the antenna selection status: ON if the SMA connector is connected to the LTE RF path; OFF if the RF is routed to the onboard antenna. By default, the SMA connector is selected.

5.2 Services

The EVB has four push buttons which can be used to reset the module or place it in recovery mode.

5.2.1 Reset operation

The module can be reset by pressing buttons SW1.

5.2.2 Recovery operation

The module can be placed in recovery mode by the following sequence: 1. Press and hold SW4 2. Press and release SW1 3. Release SW4

5.2.3 Wakeup operation

While the module is in sleep mode, press and hold SW2 to wake it up.

Pressing SW2 is only necessary if a PC terminal is not connected to the Murata module through the USB via CN14. Otherwise, the CTS signal from that USB-UART connection will keep the module awake.

5.2.4 Reserved operation

The function of SW3 is currently reserved.

6 MODULE IO INTERFACE The EVB exports the Arduino and expansion headers for access to the module IOs.

6.1 Arduino interface

The module exports the modem UART control interface to the Arduino headers. The external MCU signals are level-shifted to the 1.8V levels required by the module. To use the Arduino interface, disconnect the cable from mini-USB port CN14 and establish the following connections to the Arduino headers:

• MCU reference voltage to IOREF

• 5V supply to VIN

• MCU GND to EVB GND

• MCU UART to corresponding modem UART pins The pin assignments for the Arduino interface are shown below.

• I/Os levels are defined by IOREF to be either 1.8V/3V/5V • Signal with (DNS) is not connected by default, but can be connected with a 0Ω resister • Signal with (0Ω) is connected by default, but can be disconnected by removing the 0Ω resister

7 STARTUP PROCEDURE Unpack the EVK package and use the following steps to setup the reference PC environment and configure the EVK. The ensuing discussions are based on a PC running Windows 10 Pro. Do not connect to the Arduino interface.

7.1 Install PuTTY

Download and install PuTTY for Windows from https://www.putty.org. This is the recommended serial port console for PC serial communication with the module.

7.2 Connection to PC

Connect two USB cables from a PC to the two mini-USB ports labeled CN13 and CN14. The driver should be automatically installed for the two UART ports (A & C) associated with CN13.

Figure 11 EVK setup

The driver for UART B associated with CN14 needs to be installed manually.

• Open the following web page: https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers.

• Download the latest version of universal driver for Windows 10.

• Unzip the downloaded zip file, and run CP210xVCPInstaller_x64.exe to install the driver. After the above steps, there should be three COM ports shown in Device Manager -- one for Debug (e.g. COM8, 921600 baud), one for CLI (e.g. COM9, 115200 baud), and one for AT (COM13, 115200 baud). See below an example screenshot of the Device Manager.

https://www.putty.org/

https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers

https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers



Figure 12 COM ports assignment shown in Device Manger

7.3 AT/PPP port

By default, UART B is the dedicated AT/PPP port. Start a PuTTY session and connect to the AT port. The baud and flow control of PuTTY session, respectively, need to be set to 115200 8N1 and “None”.

If the driver is installed properly but there is no response from the module, use the CLI port to ensure that the modem is not in the u-boot mode (See Section 7.4 for details).

Figure 13 PuTTY configuration for AT port



7.3.1 AT commands

The module supports a subset of standard 3GPP AT commands and a set of proprietary commands.

• Standard AT commands start with “AT+”,

• Proprietary AT commands start with “AT%”.

All commands are case insensitive. Here is a list of some useful AT commands.

- at%ver to list versions - at+cgmi to read name of manufacturer - at+cgmm to read model number - at+cgsn to read IMEI number - at+cgmr to read software version - at%ccid to check SIM card status

7.3.2 From AT Channel to PPP Channel

The user can switch between an AT channel to a PPP channel as follows. See Section 8 for the details to create the PPP interface with a PC.

1. Connect a mini-USB cable to the CN14 (UART B) port. 2. Open a terminal shell to the AT channel COM port (the default functionality of UART B is AT

channel). 3. In order to switch to the PPP channel functionality, the user needs to run the ‘ATD*99’ AT

command. 4. After step #3, the AT channel will switch to a PPP channel, on which the user can establish a

PPP connection. 5. In order to switch back to AT channel functionality, the user needs to follow the steps below (in

the PPP terminal): a. Enter the ‘+++’ command without pressing the ‘Enter’ key. b. Wait for one second (at least). c. Press the ‘Enter’ key.

6. After step #5, the terminal will suspend the PPP and switch back to an AT channel terminal. 7. Now the port accepts regular AT commands; ATO and AT%H0, respectively, can be used to

resume and terminate the PPP session.

7.4 CLI port

The CLI port is intended for testing purposes and allows the user to enter commands to interact with the module. Open PuTTY to the CLI port. The following screenshot shows how to save the configuration as “COM9” for later use.



Figure 14 PuTTY configuration for CLI port

After connecting to the CLI port, check the prompt. If the prompt is “#”, that means the firmware is in u-boot mode. Enter “boot” command to boot it up; after boot up, the prompt should change to “>”. This is illustrated below.

Figure 15 Prompt for CLI Port

7.4.1 CLI commands

All supported CLI commands can be seen with the “help” command. The “help” command lists categories of CLI commands. Use “help <category>” to see commands under a particular category.



Figure 16 CLI Commands

Here is a list of example CLI commands.

- ver to show the current version of the firmware installed - ifconfig to show the interfaces - ping 127.0.0.1 to ping an IP address

7.4.2 Sending AT commands from CLI channel

The CLI channel supports sending AT commands to the modem, as follows: at <AT command> For example:

- at at+cfun? - at at%ccid

7.4.3 From CLI Channel to AT Channel

The user can switch a CLI channel to an AT channel as follows:

1. Connect a UART serial cable to the device’s CN13 (UART A & C) mini-USB connector. 2. Open a terminal shell to the CLI COM port (the default functionality of UART A is CLI). 3. To switch to the AT channel functionality, run the ‘serialSwitch’ CLI command. 4. After step #3, the terminal will switch to an AT channel terminal and the user can run normal

AT commands in it – there is no need for the extra “AT” as in the case with the CLI port. 5. To switch back to CLI functionality, run the ‘at%cli’ AT command. 6. After step #5, the terminal will switch back to a CLI terminal.

8 PPP LTE Connection – Windows Connect both CLI and AT port from the EVB to PC. Use PuTTY to connect to CLI port to make sure the modem is in application mode (“>” prompt is shown).



A valid SIM card inserted into the SIM slot is needed for LTE connection

Use the following steps to make the PPP connection for Windows to connect to the internet.

8.1 Creating a modem

Figure 37 Options

8. Click ‘Dial’. The CLI console should show PPP connection.

Figure 38 PPP Connection



9. Open a command prompt in Windows, and enter ‘ipconfig’. The PPP connection should

appear. If the routing is setup correctly, any internet traffic should now go through the PPP connection.

Figure 39 PPP Connection

Disable Ethernet or WiFi on the PC to ensure the internet connection is only through the LTE module.

Since the baud rate for the PPP port is 115200kbps, the data throughput is low. There are many PC programs sending and receiving packets to the network which now all use this PPP connection. Make sure any traffic heavy programs such as the web browser are closed when testing the internet connection via LTE.

9 Current measurement Configure the board as follows to use a power module that has its own meter, such as a Keysight N6705C DC Power Analyzer + N6781A power module as shown in Figure 40.

• Remove jumpers on pin 18, 19 on CN11

• Connect DC supply to both 18 and 19 which provides VBAT and VBAT_FEM, respectively

• Jump ANT_SEL (6 on CN11) to GND (15 on CN11) to select SMA antenna

• Connect the EVB to the PC

• The LTE connection can be either to a tester such as CMW500 or to the live network

The supply must be in the range of 3.2V to 4.2V and capable of delivering 1A of current.

Instead of using an external power supply, it is also possible to measure the VBAT and VBAT_FEM power consumption by using an amp meter to measure the current through the terminals of 18 and 19, respectively.

10 Firmware Upgrade Use the following steps to change the module firmware.

1. Download the PCTool software and new firmware image. Contact Murata at [email protected] for access.

2. Install both packages on a Windows PC.

3. After both packages are installed, start the Image Burn Tool utility (All Programs->Altair Semiconductor->PcTools). The new version of firmware should show up in the “Version” field.

4. Ensure that “System Header”, “U-Boot + Env”, “Flexible Partition Map”, “Application FW”, “Modem FW 1”, and “Modem FW 2” fields are all checked.

DO NOT check Configuration FS.

5. Select the CLI COM port for the UART port in Burning Options. The Baud Rate should be “3000000” and Flow Control should be “RTS_CTS”. See the screen shot below for details. Some PCs might have a hard time running at 3000000 if so try changing the Baud Rate to 921600.
