Hello, I issued a command to the BC118 module to change the baud rate to 57600. Since then the BLE module is not connecting. Each time I try to reset the module, it returns ERR. I tried changing baud rate back to 9600, but no change. I also tried to connect via Melody Smart app to reload firmware but the app does not see the module. I should also mention that this module is wired to my custom board. Its not a development board for evaluation. Please advice. Thanks, Lalit ---

Lalit, So if you are able to still send commands to the unit? This is implied but just want to make sure. If you do a scan either on your phone or from the BC118 do you see the other devices? Can you send the following to the unit toget it back to a known good config and change it from there ```auto rtr wrt rst ``` What was the command you sent to change the baud rate? Regards Matt ---

Hi Matt, I tried the restore, write, and reset commands. But BC118 does not return either ERR or OK. I’m not seeing any reply back from the BLE module. I used the UART=(BAUD) command to change the baud rate. I issued set uart=00eb Thanks, Lalit ---

Lalit, I have just done the following ```auto SET UART=00EB WRT RST ``` After the above I reset the terminal to 57600bps and it was communicating correcting at this baud rate. I took it back to 9600 and tried setting it to 57600K again but did not send the WRT command before resetting it and it remained @ 9600, are you sure you are saving it and it is still not at 9600?

I suppose, I should have done a write and reset after changing the baud rate. I added both of these commands and it worked. I then changed the baud rate back to 9600 then did a write and reset and it worked again. Thanks for your help. Lalit ---

Hello Matt, I’ve run across another problem and I’m hoping have seen it before. In testing I decided to test 2 different units which also have BC118 BLE modules. The problem I ran across was that 1 of the newer units, only connect and allows me to configure the BLE when baud rate is at 9600. If I try to configure the module at 57600 baud rate then none of the commands (restore, write, reset) work. I always get back an error. But at 9600 it works fine. Have you run across a this problem? Thanks, Lalit ---

Lalit, What are you trying to change? Can you give me an example log from power up? Regards Matt
