I have an Arduino Mega 2560 board connected to an SH-HC-08 Bluetooth Low Energy Module.
I’m trying connect the module to Blynk through the BLE Widget inside the Blynk app, but it just gets stuck on “Connecting…”, and sometimes displays the message “Connecting… Can’t connect. Please retry or choose another device.”
The devices that I have tried this on: iPhone 7+, Google Nexus 6, and HTC One M8. All 3 have BLE capabilities as far as I know.
I have tried connecting to the SH-HC-08 with AND without pairing it before directly to the phone through the Settings app.
The sketch uploaded to the arduino is blank (just an empty setup and loop), but the Bluetooth module should still connect to the app?!
As a reference, this is the Data Sheet for the SH-HC-08: https://drive.google.com/file/d/0B4urklB65vaCcEVyMm5haVVpMUk/view
What should I do?
