Blynk / Uno + ESP via serial connection problems
Posted: Sun Jun 05, 2016 3:59 pm
Hi,
I connected the Uno to an ESP-14 via Tx/Rx (like here: http://community.blynk.cc/t/arduino-uno ... -wifi/6036) but get disconnected all the time as soon as I use Blynk.run() or writeing faster than 500ms.
When virtualwrite every 500ms it seems to work pretty well. Rarely disconnect.
I saw when the disconnect happens blynk shows Buffer overflow (Blynk.print).
I further investigated and saw at nearly every command the ESP gives first "busy p..." then "OK".
I assume the "busy p..." is flooding the buffer and causes the disconnect.
I saw on one page it's probably a bug in older FW but had no luck in updating the ESP.
So... Anyone got Arduino and any ESP Working together with AT Firmware? Or isn't it possible?
