What are your plans regarding SX1212 support going forward? I'd like to be able to utilize a STM32+SX1212 combination running OpenTag next, but so far have not progressed past porting it. I'd like to know your plans, and any further advice you could give me in support of this goal.
We are not planning to support SX1212 ourselves, but the community might want to support it.... but probably not, because Semtech is more interested now in SX1276. The new chips, like SPIRIT1 and SX1276, tend to use less power than SX1212 does. This is because SX1212 takes 1.5 ms to startup, and SPIRIT1 takes only ~150us to startup. DASH7 tends to do a lot of channel samples, each one takes about 300 us + startup. So, you can do the arithmetic to find that SPIRIT1 is most efficient.
We will probably start supporting SX1276 in the near future, however.
