BC127 Firmware update problems above Melody 5.0

[bmary]

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.

Setup:
-Sparkun FT232R FTDI
PINS: RX=42, TX=41, 3.3V=(30,32,33), GND=22

Thank you

Hi Bmary,

You can try using Hercules Setup Utility tool with UART configuration as below:

Default UART Configuration

Please make sure the end of line (EOL) character used by Melody is the Carriage Return (CR) on Hercules Setup Utility tool.
I have attached the screenshot for your reference.
If possible, Could you please mark “Solution” on the answer? So the community could easily find the solution for their problems.

Thanks Donald,
Using Putty, it works by selecting “implicit LF in every CR”
