LoRa Module (semtech-baed) #217

Open quartzjer opened 9 years ago

quartzjer commented 9 years ago

This is the start of a module to support the Semtech SX1276 based radios. It's a work-in-progress!

@matthijskooijman I think I'm doing the ping right here, can you take a look and see if you can reproduce, and if it doesn't work if the logic is even correct? I'm not sure I have a "clean room" setup here to trust my hardware :)

The problem with this code is, I think, that calling the various receive functions in the SX1272 library will switch the LoRa module into RX mode, wait for a packet to be received within the given timeout period. I think it doesn't actually switch back to standby mode after reception (except when it succesfully received a packet that was for someone else?). However, I think that the next call to a receive function might mess up any pending reception.

In other words, this library is really intended for one-off receives with longer timeouts, while we would need a more asynchronous polling type of approach instead.

Given that I don't really like the library code itself (lots of similar functions, some magic constants, LGPL license), I'll have a look at the LMIC code instead.

:+1: it was just used as the fastest way to validate the hardware was hooked up right, you're the only analysis so far :)
