Once again in plain text, only - sorry for frogetting to set the switch in my mailtool.... Hi Dan, Hi Walter, thank you for your investigation. rf69_get_modulation, rf69_get_lna_gain, rf69_set_lna_gain: Seems like I messed up a few things :-/ In the beginning, the defines were left-bound "real" values, like you can see for the LNA_GAIN values. Later on, I deceided not to use left-bound "real" values, but to leave the bits at the position, they have in the register. These two impelemtation types are mixed up here. Sorry. Result: The shift is obsolete and the LNA_GAIN defines are old-style and need to be reviesed. I will send a patch with a proposal in approx. half an hour. rf69_set_deviation: Yes Dan, bitwise negate was intended. Once again, thanks a lot for your investigation, Marcus Thanks a lot, Marcus > Dan Carpenter <dan.carpenter@xxxxxxxxxx> hat am 19.
