We use about 5 rf module with Digimesh protocole (0x804B). These modules send GPS data periodically (every 5s with a variable delay).
The experiment works well for a few days...and after these few days, some RF modules stop transmitting but don't say that they don't emit : no error.
It is possible to communicate with these modules thanks to the UART :
RF status : some TX or RX errors (sometimes more than 65k) but it s quite normal after few days
ND : no other module
We don t use sleeping devices
As soon as we soft-reset one of these modules all is OK
Is there a known bug in the firmware 0x804B ?
