GSM A6 BOARD
From the Developers of ESP8266
After ESP8266, which broke all the market records in IOT, providing the cheapest WIFI chip in the market,
Now AI Thinker seems to be promising with a new module in the market, A6 GSM/GPRS Module.
This A6 GSM/GPRS Module is now a big competitor for SIM900 series module.
It supports dual-
The board features compact size and low current consumption. With power saving technique, the current consumption is as low as 3mA in sleep mode.
It communicates with microcontroller via UART port, supports command including GSM 07.07, GSM 07.05 and Ai-
It has a few really nice features that you may not have considered usefull.
A6 GSM AT COMMANDS
How to use it:
1. Connect UART_TXD to RX of the FTDI
2. Connect UART_RXD to TX of the FTDI
3. Connect GND to the GND of the FTDI
4. Connect VCC5.0 To the PWR_KEY pin.This acts like CHIP ENABLE.
5. Connect a Micro Usb for the power(with any smartphone charger)
6. After 4-
You can open any serial monitor software like PuTty , select the port alloted to your FTDI and choose 115200baud.
Input “AT”, and if you see “OK” it works!
The A6 GSM requires a CARRIAGE RETURN after every AT command.
This can be done easily with the SET MACROS function of the TERMINAL software. Here you can store AT commands
followed by a $ sign & 0D. $ sign is to Append & 0D is the ASCII for Carriage Return.
The good new is the AT commands are very close to the Commands for others Gprs/Gsm modules like SIM800/SIM900 .
The CIPMUX command can’t be used, maybe it’s CMUX
How to make a call ?
ATD+the phone number
For example: ATD944xxx
Push enter and you will recieve the call.Note that no semicolon is required as in SIM900.
The no. will be dialled even if you use a semicolon.
How to send a message ?
AT+CMGF=1 to change to TEXT mode.
>(write the message here) (push Ctrl-
CTRL+Z can be sent using the ASCII code 1A.
You can see all your previous message with:
for an another message change the number
