Hi,
I heard that changing the bitrate could increase your communication distance. Is that true?
If so, I'd like to play with it. I only saw a previous thread talk about changing the bitrate by modifying these lines in the .cpp file:
#define RF_BITRATEMSB_CUSTOM 0x2e
#define RF_BITRATELSB_CUSTOM 0x66
Is that how we're suppose to change the bitrate? I read the default is 4800kbps, but how does the different kbps translate to those MSB and LSB values?
The rule of thumb is, the lower bitrate (essentially - frequency) is, the further you can transmit.

Well, no what I meant is to use the same carrier frequency (these wireless modules only transmit/receive on a single frequency), but change the bitrate/baud.
Slowing bitrate in this case would not affect distance really, but the impact would be on data quality and number of missing packets. If you want to get better redundancy you'd better slow down bitrate and do more repeats. That's in general.
I honestly have no idea how this RF module works, but I assume it follows these principles. Low bitrate would give you more stable reception.
