# A6lib
|
|
|
|
An ESP8266/Arduino library for communicating with the AI-Thinker A6 GSM module.
|
|
It will probably also work with other GSM modules that use the AT command set,
|
|
like the SIM900.
|
|
|
|
## Details
|
|
|
|
This library is an adaptation of
|
|
[this sample module](https://github.com/SensorsIot/A6-GSM-Module). It is still
|
|
very incomplete, but at least it works somewhat. Please feel free to issue pull
|
|
requests to improve it.
|
|
|
|
## Usage
|
|
|
|
If you have the A6 breakout board, connect the Tx and Rx pins to your ESP8266.
|
|
The example assumes the TX pin is connected to D5 and the RX to D6. A6lib can
|
|
power-cycle the module if you connect a MOSFET to a pin and control the A6's
|
|
power supply with it.
|
|
|
|
For a sample circuit that uses this library, have a look at [the A6/ESP8266
|
|
breakout board](https://gitlab.com/stavros/A6-ESP8266-breakout/) I designed.
|
|
|
|
The A6's PWR pin should be permanently connected to Vcc (if you think that's
|
|
wrong or know a better way, please open an issue).
|
|
|
|
The code looks something like this:
|
|
|
|
~~~
|
|
// Instantiate the class with Tx, Rx (remember to swap them when connecting to
|
|
the A6, i.e. connect the A6's Rx pin to D6).
|
|
A6lib A6c(D6, D5);
|
|
|
|
// Initialize the modem, rebooting it if it fails to become ready.
|
|
do {
|
|
// Power-cycle the module to reset it.
|
|
A6c.powerCycle(D0);
|
|
} while (A6c.blockUntilReady(9600) != A6_OK);
|
|
|
|
// Start and place a call.
|
|
A6c.dial("1234567890");
|
|
delay(8000);
|
|
|
|
A6c.hangUp();
|
|
delay(8000);
|
|
|
|
A6c.redial();
|
|
delay(8000);
|
|
|
|
// Send a message.
|
|
A6c.sendSMS("+1234567890", "Hello there!");
|
|
|
|
// Get an SMS message from memory.
|
|
SMSmessage sms = A6c.readSMS(3);
|
|
|
|
// Delete an SMS message.
|
|
A6c.deleteSMS(3);
|
|
|
|
callInfo cinfo = A6c.checkCallStatus();
|
|
// This will be the calling number, "1234567890".
|
|
cinfo.number;
|

This library doesn't currently include any code to connect to the internet, but
|
|
a PR adding that would be very welcome.
