And i have an another question. How can i reboot the board in software?

Hi, please try the code attach.

This code is for AT command to control GSM of LinkIt ONE, you can make voice phone call, write/read a SMS and so on.

  1. AT_CMD_Arduino should put to libraries folder of Arduino, such as D:\LinkIt-ONE-IDE\libraries
  2. Upload AT_GSM to LinkIt ONE, then open serial monitor
  3. Input “AT+SHOWCMD” to get the AT command

Please have a try, and tell me if it’s work, thanks~ (60.6 KB)

thanks for the answer :slight_smile:

but i’m sorry because the AT command doesn’t work… Look my attachement

Hi, did you send a new line at the end of command(\r\n or \n), it’s needed.

yes when i sent CR: carriage return, it is equivalent to \r

I think i meet the same problem: no more incoming SMS after some time.
Only a hard reset is ok to retablish a good working state.

Have you find another solution ? have you alway the same problem ?

I"m French too. using Free network.

With the latest SDK and the firmare 1.1.05, all problem are solved!
