1. Overview

MiCO-AT firmware 1.1

MiCO-AT firmware developed by MXCHIP is one software system which could be easily and conveniently used to

set wireless network on embedded device.

Users can set the Wi-Fi connection without any programming work.

MiCO-AT firmware version: EMW3162, EMW3165.

2. Operation Modes

Operation Modes 2.1

1. DTU mode

Module connects Wi-Fi automatically by the preset setting. It receives the data from serial and packs it as TCP/UDP

package, then sends it out by Wi-Fi. At the same time, it can also receive the TCP/UDP package by Wi-Fi and send

the data to serial.

2. AT command mode

In this mode, it could set parameterss and control the module by AT commands.

3. Boot mode

In this mode, it could update the firmware by serial with Ymodem protocol.

4. Testing mode

In this mode, it could do some testing work by serial.

Initial operation mode 2.2

The firmware could lead the module into different operation mode by testing the PIN status of BOOT and STATUS.

Table 1 operation mode

BOOT STATUS Operation mode

0 0 Testing mode

0 1 Boot mode

1 1 DTU/ AT command mode

Operation mode switching 2.3

The firmware could lead the module into different operation mode by testing the PIN status of BOOT and STATUS.

1. DTU mode -> AT command mode

(1) Input “+++” by serial, it returns “a” after module receiving the “+++”;

(2) Input “a”, it returns “+OK” and goes into AT command mode after module receiving the “a”;

2. DTU mode -> AT command mode (Close WLAN, TCP and UDP)

(1) Input “+++” by serial, it returns “a” after module receiving the “+++”;

Input “b”, it returns “+OK”, goes into AT command mode and closes WLAN, TCP, UDP after module


RM1021EN

receiving the “b”; It needs controlling the time interval at typing “+++” and “a” in order to ensure the module going

into the right mode.

Figure 2 DTU mode

3. AT command mode -> DTU mode

It switches to DTU mode by command “AT+QUIT” at AT command mode.

Default setting 2.4

It could set the default settings on the base of factory settings. Users can contact with MXCHIP to add some new

commands or settings whether the default ones are not satisfied.

1. Factory settings

(1) Serial setting: baud rate (115200), data bit (8), stop bit (1), parity (none), flow control (none).

(2) Wi-Fi setting: mode (Soft AP), ssid (MXCHIP_XXXXXX), passward (none);

(3) IP setting: IP address (10.10.10.1), net mask (255.255.255.0), gateway (10.10.10.1);

(4) DHCP server: Enable;

(5) Bonjour server: Enable;

(6) TCP server: Enable, Port: 8080;

(7) HTTP server: user (admin), password (admin);

2. Restore default settings

(1) Restore user factory settings:

Press down “EASYLINK” button for 5s at all modes;

Input “AT+FACTORY” command at AT command mode;

(2) Restore MXCHIP factory settings:

Input “AT+FCLR” command at AT command mode;

PIN arrangements 2.5

UART PINs 2.5.1

In AT firmware, module has different UART PINS at different modes.

Website setting 3.1

Connect PC to Wi-Fi module by Wi-Fi. The default SSID is MXCHIP_XXXXXX (XXXXXX is the after 6 numbers

of MAC address). Open the browser and go to “10.10.10.1”. it will show as below.

Default user: admin.

Default password: admin.
