NimBLE Porting Layer builds OK on #RISCV #BL602 #FreeRTOS yay! ... Let's call these Event Queue functions to process our received #LoRa Packets

https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu#nimble-event-queue-functions

Fortunately #FreeRTOS has a function to check whether we're in a #RISCV Interrupt Handler ... "xPortIsInsideInterrupt"

NimBLE Porting Layer hasn't been ported ... To #RISCV ? 🤔 ... Let's fix this for #BL602 #LoRa

Maybe #PineTime can help #BL602! ... The NimBLE Porting Layer defines Multitasking Functions for #FreeRTOS ... Let's call them to handle #LoRa Interrupts

https://lupyuen.github.io/pinetime-rust-mynewt/articles/dfu#nimble-stack-for-bluetooth-le-on-pinetime

Now that #BL602 can handle #LoRa Packet Received Interrupt ... Let's defer the LoRa Packet Processing from the Interrupt Handler to the Application Task ... How shall we do this in FreeRTOS? 🤔

#BL602 GPIO Interrupts hanging could be due to the way we handle multiple GPIO Interrupts ... Let's revisit this when we can trigger multiple GPIO Interrupts from #LoRa SX1276
