Well the range test with the reliable datagram was hardly worth me putting some sandals on, it faded out at about 7m range !
I had looked at the data to the module, and it looked so fast compared to my normal projects.
I couldnt find a way to change the data rate, so I delved into the RF22 library cpp file, and changed the power to 17 dBm, and the baud rate to the one I used on the simplex mode. ( i have no idea what it means ! )
There is a spreadsheet to calculate the set up , but it doesn't work in openoffice
My changes :-
// setModemConfig(FSK_Rb2_4Fd36);
setModemConfig(GFSK_Rb2Fd5);
// setTxPower(RF22_TXPOW_8DBM);
setTxPower(RF22_TXPOW_17DBM);/
I can now walk 50m to the end of my road with it still working, and I am going to take them out on a straight road to test.
It did fade through 3 buildings, but my appication is in the open air...
