I found a post with a tested library mod for 19200 posted by Felix but couldn't find something similar for 1200bps. Does someone have them? I found the following:
// /* 0x03 */ { REG_BITRATEMSB, RF_BITRATEMSB_1200}, //default:4.8 KBPS
// /* 0x04 */ { REG_BITRATELSB, RF_BITRATELSB_1200},
// /* 0x05 */ { REG_FDEVMSB, RF_FDEVMSB_2000}, //default:5khz, (FDEV + BitRate/2 <= 500Khz)
// /* 0x06 */ { REG_FDEVLSB, RF_FDEVLSB_2000},
But in the 19200 config there are a couple more registers.
Thanks,
