- Only Android App detected the BLE, not iOS.
- The Feather M0 received data from Blynk but Blynk app was not receiving any data from Feather.
So, in brief,
- Is iOS is going to be supported (master-peripheral mode).
- Can Android app receive data from BLE devices (nRF51822 chip) which Feather is built on top of it?
I’ll receive the kit in few days and hope to get more insights if someone successfully tried it out on both platforms with send/receive data.
Thanks
