BLE client sketch module 5 unit 4 not displaying data on OLED but okay on nrf mobile app

Judson Belmont asked 2 years ago

I’m almost there on ESP32 BLE module 5 unit 3 and 4. My server program is running and producing and broadcasting the DHT11 data. I can receive it on the nRF mobile app fine. The client program loads and the oled displays “DHT SENSOR,” the serial monitor says “starting Arduino BLE client application.” But that’s where it stops. I’m connected to a MAC and Bluetooth is enabled. I’m missing something. Appreciate any guidance.

Hi.
Have you tried rebooting/resetting the ESP32 running the client sketch?
What does the client board display on the Serial monitor?
 
The server sketch needs to be running before the client sketch. Additionally, disconnect from the nRF app.
 
Regards,
Sara
