I am unable to change the baud rate using the AT+IPR command. For example, I issue the command
AT+IPR=19200<cr> and I do not get a response. I thought that perhaps I didn't get a response because the baud rate had changed but I am able to issue other commands (ie. AT<cr>) and get the OK response. If I issue the
AT+IPR=115200<cr> command I get the OK response. Any help would be much appreciated.
