I have some Communication problem with two CC2543 devices communicating with each other.
Aproximately 20% of all button communications are not correctly received.
How off can we be and still have a reliable communication between two CC2543 devices running in 2MBps, 320kHz deviation with a 7byte payload? It runs in auto mode with 10 re-transmissions in case the com fails. And still ~20% of the coms is not received.
We have measured with a spectrum analyser the baseband frequency on both sides. This is the result:
Transmitter - 2420,06MHz
Receiver - 2420,25MHz
I found this in the datasheet. Is that what we can expect for our product aswell? 300kHz tolerance?
