Forum Post: RE: Right GPIO pin for TMDXEVM8148 Evaluation Module (Rev D) to enable BT with WL1271

Santosh,

Which GPIO you are using and is it connected from processor to WL1271 module - is there a way you can probe if this IO line is pulled high when you try to turn BT On? If not then it explains why no response from chip. You should start with default baud-rate - 115200 to start with.

Thanks,
Naveen
