Thanks @PeteKnight .
I tried it and now I can’t connect… After reading a bit I get the impression
#define BLYNK_USE_DIRECT_CONNECT is actually necessary for Bluetooth / BLE.
Any other ideas?
BTW, I must say I’m surprised BLE/Bluetooth is not more popular. I’m working on a wearable, so it seams to me like an obvious choice.
Perhaps it’s just because it’s not mature enough…
(and @Mukhtyar_Singh , not sure I understand how this is relevant to this post… Sorry, can’t help you)
