I recently purchased the GSM Click module and have been trying to talk to this board via uart using the CC3200 launch pad, but I was not successful in receiving proper response from the GL865 so far. Has anyone been working on this and could share some experience?
My settings are as follows:
- Connect TX on the GSM Click to UART1-TX (pin 1) on the CC3200
- Connect RX on the GSM Click to UART1-RX (pin 2) on the CC3200
- 3.3V
Then I have been trying to send AT command using both 115200 and 9600 baud rates to the GL865 but neither baud rate gave me an OK response. In other words, I was sending string "AT\r" over uart and was expecting to see "OK\r" in response but the response always returned with random bytes.
Any help on this would be greatly appreciated.
