BL602 vs ESP32 🤔

For #NuttX on #BL602, we use SPI Mode 1 instead of Mode 0 ... To work around the SPI Mode Quirk

Let's use an NB-IoT Antenna ... As the #LoRa Antenna for #PineDio Stack BL604 @PINE64 ... For now

Our #NuttX App reads an SX1262 Register ... But it returns garbage! There's a workaround for this #BL602 SPI Quirk

https://github.com/lupyuen/incubator-nuttx-apps/blob/spi_test/examples/spi_test2/spi_test2_main.c#L90-L119

Now our #NuttX App is ready to read an SX1262 Register over SPI!
