Maximum Baud Rate #54

Open flybrianfly opened 1 year ago

flybrianfly commented 1 year ago

Am I correct, guessing from this file that the maximum supported baud rate is 921600?

kriswiner commented 1 year ago

I think this is right. Not sure how much higher you might need to go....

921600 is the limit.

May I ask why this high transfer rate ?

Transferring data between a Ladybug and an ESP32. The Ladybug is doing the heavy lifting to determine the states of a vehicle and the ESP32 is wirelessly broadcasting those states to a display - don't have a hard requirement on baudrate, just trying to minimize latency. I can work on compressing the packet size, but if I could increase the baudrate, that either provides an easier solution to reducing latency or provides options to reduce it further.
