Indeed, looks like it won't be enough to just keep it as alias. I added a full class implementation for LLCC68, so now it should check bandwidth and spreading factor properly.
The only diff in datasheet between the two is one line:
Not all SF are available for any bandwidth with the LLCC68
But it doesn't say which combination is valid. Any idea?
LLCC68 868 is easier to buy than SX1262 868 on ali
@mrx23dot I would suggest seaching the datasheet again: it does say which combinations are valid.
EDIT: I would also like to point out that the LLCC68 has some issues for LoRaWAN precisely because of this limited selection of SFs, so if that's your use case, just buy an SX1268 and save yourself the hassle.
Oh yeah I missed that one in diff, thanks! That means it's unsuitable for default preset in Meshstastic.
According to the spec, LLCC68 support SF5~9 @ 125K BW, SF5~10 @250K BW, SF5~11 @ 500K BW When I was playing, I found it always failed with code -20 if SF >9 when it was doing initialization. Looks like there are still differences between SX1268 and LLCC68.
Could you help to check? Thanks!
