  • Hi guys, so I’ve been having a problem with the UART on the SM130. For some reason I can’t get it to communicate with me. All I’m trying to do is send the command to read the firmware version (FF 00 01 81 82 –from datasheet) but no response. I also tried other commands but again, no response. Whenever I reset the module’s power I receive this message: FF 00 08 81 55 4D 20 31 2E 33 64 in which the payload data is “UM 1.3d” which I assume is the current firmware version. This makes me think that my UART is connected correctly (at the default 19200 baud). Has anyone else had any issues like this? Thanks!

No public wish lists :(
