serial comm. in embedded system. Hopefully this is the right place to
ask such question.
I am working a program that has zigbee cc2530 SoC communicate with
host device, mobile phone, through serial interface. The baud rate is
set as 115200 Kbps at both zigbee chip and host device. When I ping 1
byte from host dev to zigbee, and zigbee echo back the response, the
RTT was around 10ms. I think this has to do with some uncertain delay
on the serial link. Anyone could show some guidance how to get around
the high overhead on serial link? Or this is something unavoidable?
thanks a lot in advance!!!!
