I started to work with Bluetooth and limited in experience, I hope someone will be able to assist me with trouble shooting firmware update with the BC127.
I purchased couple initial module loaded with Melody 5.0. So far so good, I soldered directly on the module pins and got the module responding as it should. There are some command in the newer firmware I would like to use. That were the issue start, any firmware I install above 5.0 gives me trouble. I get the outputs from commands but all in one line and overwriting each others. If the chip idle for little bit, it no longer respond to any commands, and I get ERROR 0x0012 ( command not recognized).
When I reboot the module, it goes the same for a while.
