We have a base station which utilises the Q2687 2G module to send SMS during an alarm situation. The base station has a microcontroller which drives the Q2687 via RS232 with AT commands.
Being the same footprint, the Q2687 module can be replaced by the Q2698, is this correct?
However, the current Q2687 has some customised AT commands. Unfortunately, we can’t change the Microcontroller software.
Are the customised AT command able to be transferred to the Q2698 or is there a way of reverse engineer and edit these commands to suit Q2698 ?
I have monitored the AT messages from the RS232 communication port. Will post it out if any help.
Please help. Thanks. We have 200 over base station to upgrade.
