Really hope someone can look into this issue!

kenken64 commented 5 years ago

can someone from blynk teach me how to deploy and debug so i can help

kenken64 commented 5 years ago

any update on this issue ?

kenken64 commented 5 years ago

I try updating to the latest firmware also no luck

if there isn't any serious support for microbit why did blynk post an article like this? http://help.blynk.cc/how-to-connect-different-hardware-with-blynk/arduino/bbc-microbit-arduino-ide

Refenz commented 5 years ago

@kenken64 Blynk team is busy developing a new product and unfortunately this leads to delays in communication. For communication and troubleshooting use: https://community.blynk.cc/ Please create a topic in an appropriate section. Someone from the participants can help you in solving this issue or give advice. Note: Blynk developers are also monitoring the community

rei-vilo commented 5 years ago

Already done. Please refer to https://community.blynk.cc/t/problem-with-example-bbc-micro-bit-arduino-ide/34942

FedericoBusero commented 5 years ago

Not the packet is too big, it's the buffer that is too small ... https://github.com/FedericoBusero/blynk-library/blob/master/src/Adapters/BlynkBLEPeripheralSerial.h

Also replaced the UUID's with Blynk's UUID and changed WriteNoResponse to Write Still to do: use Blynk's FIFO

FedericoBusero commented 5 years ago

I created a pull request with a fix https://github.com/blynkkk/blynk-library/pull/463

vshymanskyy commented 5 years ago

The fix was merged. Let us know how it works!
