BC118 returns ERR for every command

IoT Modules WiFi and Bluetooth Modules

Hello,

I’m working with BC118 module and first I was developing with BC118 Discovery Kit that has V3.4 of MelodySmart, and it was accepting commands normally.

Now I am with my own PCB and the MelodySmart has the version v4.0. In this stack I always receive ERR when I send any command (set BOND=ON for example).
I can get status, verify the version, reset.

Another thing is that when I connect the MelodySmart App I’m unable to exchange data in the v4.0.

I have looked the updates in v4.0 and the schematics and everything is ok, is there anything different that I need to take care? About pins, initialization…

Thanks.

@abiegelmeyer,

So when you power the unit on do you get the normal start up text coming out of the unit at your micro UART?

Hello mlw,

Thanks for reply.

Yes I have the normal startup showing READY in the end:

Capturar

I could restore all configurations to default including.

Anderson,

Just re read your post, you can send sts, ver and rst and the commands respond correctly? Can you send cfg to get the configuration of the unit out to see if something is preventing it from allowing the BOND command to be set?

Mlw,

Thanks for reply.

Yes, I can. Below you can find the currently CFG:

Comparing with the v3.4 config only the BOND parameter is diffenrent (v3.4=off and v4.0=on) and other that are new like GCEN, INDE, RELA.
