Join is attempted on disabled channels #88

Open dlarue opened 7 years ago

dlarue commented 7 years ago

after LMIC_disableChannel(x) is called for say channels 0-9 and again for channels 11-72 I still see join attempts on all of the US-915 subband2 frequencies. Is this a function of TTN/server doing the join requests or does the library do any handshaking to let the server know what channels are available?

@dlarue I'm running across the same issue. Any updates on your end?

I have the same problem. Why is it joining on channels I disabled?

dlarue commented 5 years ago

This fork seemed to be more actively developed - can you try it and see if it has the same issue and report back here?

MCCI's library uses LMIC 1.6 and doesn't have this issue.

The bug with this lib is that it doesn't take the disabled channels into account on rejoin attempts.

I used this (https://github.com/async-la/arduino-lmic/commit/9f29f6f8cedd77a6490361990536e51bedad1d5a) hack to force the use of TTN's sub-band, but the better option would be to use library mentioned above.
