SX1262 will trigger a GPIO Interrupt on #NuttX OS when it receives a #LoRa Packet ... We wait for the GPIO Interrupt to be Signalled in a Background Thread
https://github.com/lupyuen/lora-sx1262/blob/lorawan/src/sx126x-nuttx.c#L742-L778
Here's how we check the SX1262 Busy Pin on #NuttX OS ... By reading the GPIO Input

#LoRaWAN runs neater on Apache #NuttX OS ... After implementing Timers and Multithreading with NimBLE Porting Layer ... No more polling and sleep()!

@lupyuen If you are used to Lora, you will get very disappointed with Zigbee. I used to use Zigbee, but it was a nightmare... no reach, and almost no actual interop between manufacturers, even though that was a requirement.

@lupyuen I can't really say quite why, but somehow, the more broken the Pinephone (Pro) is, the more I love it. I think it's the sense that this is something that WILL be great, and all the shortcomings now, are just low hanging opportunities to quickly improve, just waiting to happen. Improvements that even I, as a non coder, can help with. (Bug triage, reporting, testing, graphic design,documentation etc). 📱 💕

And yet I'd bet that those devices are still recording and surveillance them.
To build NumBLE Porting Layer on #NuttX OS we need to enable: 1️⃣ POSIX Timers & Message Queues 2️⃣ Clock Monotonic 3️⃣ Work Queues 4️⃣ SIGEV_THHREAD

Our #NuttX App was waiting for the #LoRaWAN Join Request to be transmitted before receiving the Join Response ... But because we're polling SX1262, we missed the Join Response ... Let's fix this with the multithreading functions from NimBLE Porting Layer
