Turning off OTA fixes the issue. Server only sends "ota url" command with OTA enabled.

1)залил дефолт скетч
2)логин на КУА
3)запустил BlynkBoard provisioning
4)железка законектилась и сразу отконектилась
5)через пару сек. появилась на секунду онлайн и снова офф

@vshymanskyy What is the status of the issue? The customer-launch is scheduled for early September.

Refenz commented 7 years ago

@vshymanskyy After 4 days @doom369 will go on vacation and fix the server side will be difficult. I think it's better to fix the problem before that. Any news?

vshymanskyy commented 7 years ago

@Refenz I'm checking it

Cannot reproduce. Tried several times, sometimes i see several connection attempts, but eventually it connect to server, possibly after 1 reboot:

Woa!!!

After 10-15 secs it's always back online.

vshymanskyy commented 7 years ago

@Refenz can you re-check and confirm if it recovers connection?

Refenz commented 7 years ago

@vshymanskyy Yes, it seems all right. You can close it. It seems the problem was in a very bad wi-fi connection. Thank you.
