Long story short: I need to pair these devices:
- Arduino UNO with Seeed BLE Shield
- Adafruit Feather 32u4 Bluefruit LE.
The Seeed shield is configured and able to connect and communicate via the UART to an Android phone by HM BLE Terminal app from Google Play Store.
I can also connect the phone and Feather. The two independent connections work really well but a problem occurs when connecting the Seeed shield with Feather.
Connection isn't troubling No errors are reported but I can't send/receive any data via the serial monitor (I'm using bleuart_cmdmode or bleuart_datamode from the Adafruit examples).
Basically my question is how to make them work: HM-11 module with BLE and the Adafruit board (nRF51822 chipset from Nordic).
