It might be time to look at the BLE module. I understand that, by "LE", they really mean it and there is a huge difference.
Didn't get more information. Sophos dont like to visit their webpage because of a threat. Is this Module Pincompatible to HC-05? Can you share the datasheet?
Anyway. There are these options in the manual. Also they are not very good documented I will try it. Why? First of all, because I can. Still like hacking and trying everything I can before i give up. And second their already soldered into the mainpcb and I couldn't see a way of desoldering them without destroying.
So thanks for the suggestions. It may be plan B.
