Getting the old UART handling back?
Posted: Tue May 17, 2016 7:09 amHi all,
We've upgraded the esp arduino library from 2.0.0 to 2.2.0 recently, only to realize that the UART buffer handling has been changed from SW buffers to HW buffers. Resulting in a RX-buffer limit on 128bytes (because it's hardware buffers). Well, we need atleast 2048, so we basicly need the old Serial / UART handling again? But how is that done?..
(Yes, we've tried to empty the hardware buffer fast as possible but it is not fast enough - it takes around 8ms to fill up the HW buffer, and we have some tasks taking up to 10-12ms).
