Hm-10 BLE specific Firmware to connect with Blynk

Maybe it is filtered out due to not supported UUIDs - we have a list of supported devices for BLE widget:

But it seems that your device should be supported. I’ll update later logging build in the thread concern by BLE issues: BLE connection problems / a question to all blynk users - if you have time you could use it and send me a log generated by the app, so I’ll check is this device filtered out from scan list.
