Ryan Berninger asked 7 years ago

Pretty new to this, and trying to follow the videos, but every time I connect my client (nRF Connect IOs) to my Hiletgo NodeMCU ESP32s, I keep getting this message after Waiting for a client connection to notify..
BT: Call back not found for application conn_id=3
What am I doing wrong?

Hi Ryan,
Sounds like this issue is still open on GitHub (the same conn_id=3 error message). What do you see in your Arduino IDE serial monitor when you try to connect to the app? Just the “waiting for a client connection to notify” message?
