Module installation

Installing the WBC-4G v.2 module in the Wiren Board 7 controller

When ordering modules bundled with the Wiren Board controller, we install them in production - you only need to configure the modules in web interface of the controller.

If you bought the modules separately, install them yourself:

1. Disassemble the controller case.
2. Insert the module, observing the polarity: the protrusion on it must fit into the groove on the controller board.
3. Insert the SIM card
4. Reassemble the case.
5. Screw the external antenna onto SMA female.

When mounting in a metal shield, position the antenna outside for reliable radio communication.

Configuration

After physically connecting the modem, it should be added to the controller configuration:

1. In the web interface, go to the Settings → Configs → Hardware Modules Configuration section, select the Modem slot.
2. In the Module type drop-down list, select the type of the installed module.
3. Click the Save button. The controller will enable the ports required for the modem to work.

To remove the module, select the type None.

After configuring, turn on the modem using the command wb-gsm on and set up the connection to the mobile operator.

Info

Обмен данными с модулем идет через последовательные порты /dev/ttyGSM и /dev/ttyUSBx (обычно это /dev/ttyUSB0 и /dev/ttyUSB1).

Default Connection Parameters

Value	Parameter	Description
Auto-bauding	Baud rate	Speed, bit/s. Set to 115200 in the connection program settings. After connecting, send AAAAAAAT to the modem, and it will automatically determine the speed.
8	Data bits	Number of data bits
None	Parity	Parity bit
1	Stop bits	Number of stop bits
Off	Hardware flow control	Hardware flow control
Off	Software flow control	Software flow control

При необходимости параметры соединения можно изменить через AT команды.

Setting up an internet connection

See the instructions for setting up internet via a 4G modem in the article GSM/GPRS. Please note that the 4G network does not operate in all regions. To check the current settings, use AT+CNMP?.

Switching the modem to the automatic network type selection mode is carried out by the command: AT+CNMP=2

Documentation

AT commands:

• Файл:A7600 Series AT Command Manual V1.02.pdf for pre-B05 chips;
• Файл:A76XX Series AT Command Manual V1.07.pdf for versions B05 and newer.

You can find out the chip version number with the AT command at+cgmr , which returns a string with the number, characters 6 to 8 will be the chip version. How to send an AT command.

For example, in the example below, the chip version is B05:
