RN42 bluetooth module with with pro mini

Post by Shilpa17 » Wed Jul 25, 2018 8:48 am

Hello,
I have been having this issue for a while now. I am incorporating pro mini into my project, where I have a myoware sensor connected to pin A0 and A2. The myoware modules are powered externally. RN42 bluetooth module is connected to pro mini and the stat LED in the bluetooth module blinks and gets paired as well. I am trying to visualize the data through the app coolterm. However, the transmission isn't happening. All the components are powered. I am powering up promini externally through DC supply at voltage level 7V.
My connection between RN42 and pro mini are as follows:
Pro mini RN42
Vcc Vcc
GND GND
TX RX
RX TX

Appreciate your help in advance.
