I am experimenting with Arduino Mega 2560 and HC-08 BLE module (a clone of HM-10).
My results are:
Never use SoftwareSerial to comunicate with HM-10 because it is the reason of “Packet too big” error
BLE widget on Android app cannot connect. I personally tested Android 8 (Samsung A5 and Xiaomi redmi Note 5), Android 5.0.1 and Android 4.4.2 with no succes. May be HC-08 is not a fully compatible HM-10 device. Do you know if the original HM-10 works like a charm?
iOS app works better but it is not perfect. BLE widget connect to HC-08 but device is not reported online even if communication is established. Data from the app to arduino works. Any communication from arduino to the app doesn’t work. BLYNK_WRITE(vPin) works but virtualWrite() doesn’t update virtual pin on the app.
When the BLE widget will be out of the beta phase?
