LoRa version problem #5

Closed pyrotechnik closed 2 years ago

pyrotechnik commented 3 years ago

Hello, I would like to use your library for SX1276. But I have a problem with verifying the version of the module. I get an answer of 0 and if I switch the MISO with MOSI I will get 255. I have already tried a different connections and I use reset LoRa modul using the RST pin, but still without results.

@pyrotechnik I'm having the same issue. Did you solve this? Can you share?

pyrotechnik commented 2 years ago

Hello, unfortunately not. I bought an SX1278. And here everything works properly.

Meanwhile I figured out what my problem was: the SPI was configured at 40MHz and 4 bits. I changed to 10MHz and 8 bits and started working.

Great that you've found the problem yourself. BTW, I recently fit the same stuff: for some reason CubeMX set non default SPI params, so always great to double check whatever is being generated by cubemx.

Closing this one as resolved
