Porting the #LoRa SX1262 Driver from Linux to Apache #NuttX OS ... All shall be explained in this article

https://lupyuen.github.io/articles/sx1262?1

Our plain and simple #NuttX #LoRa SX1262 Library is (nearly) done! Porting the library from Linux to NuttX wasn't so hard ... Moving on to LoRaWAN real soon!

Our #NuttX SX1262 Library correctly receives the #LoRa Message transmitted by #RAKwireless WisBlock! 🎉

Here's how we receive #LoRa Messages with our #NuttX SX1262 Library ... Eventually this will be triggered by GPIO Interrupt (instead of polling)

Now our #NuttX SX1262 Library shall receive a #LoRa Message ... Transmitted by #RAKwireless WisBlock

https://github.com/lupyuen/wisblock-lora-transmitter

#LoRa Message transmitted by our #NuttX SX1262 Library ... Received OK by RAKwireless WisBlock! 🎉

https://gist.github.com/lupyuen/5fdede131ad0e327478994872f190668

Let's use #RAKwireless WisBlock to inspect the #LoRa Message transmitted by our #NuttX SX1262 Library

SDR shows the #LoRa Chirp transmitted by our #NuttX SX1262 Library 🎉 ... Let's inspect the message with a LoRa Receiver

Our #NuttX SX1262 Library transmits a #LoRa Message ... We sniff the message with Airspy R2 SDR

Now we transmit a #LoRa Message with our #NuttX SX1262 Library

https://github.com/lupyuen/incubator-nuttx-apps/blob/sx1262/examples/sx1262_test/sx1262_test_main.c#L237-L253

Yesterday we created an empty #NuttX Library for SX1262 ... Today we fill in the #LoRa SX1262 Driver Code
