Sorry to bother you guys - I’d like to reopen: [SOLVED] Bluetooth BLE support for Adafruit Feather Bluefruit LE
Specifically I’m (still) having issues connecting Blynk to the Adafruit Feather 32u4 BLE board to android. The board appears to be transmitting data to the app, but the app doesn’t seem to be parsing everything.
My test is to write data from the board to the app every 10 seconds.
What I observe is that the app doesn’t keep up and eventually the board times out.
I have a hypothesis - I’m seeing out-of-order sends, perhaps this is confusing the Android code. Here’s an example where message 0E is sent before 0D:
[58159] <[06|00|0E|00|00]
[58202] <[14|00|0D|00|06]vw[00]3[00]3
Could this be the issue?
