#LoRa SX1262 Driver for #BL602 ... How it works

https://lupyuen.github.io/articles/lorawan?9#lora-transceiver-driver

Let's dive into the #BL602 Drivers for #LoRa and #LoRaWAN

Magical Pin DIO1 on RFM90 #LoRa Module @PINE64

Here's how we connect #PineCone #BL602 @PINE64 to Pine64 RFM90 #LoRa Module

#LoRa Concentrator Doc made me wonder ... Could our #LoRaWAN Gateway be dropping packets from #BL602 because we sent the wrong Sync Word? Yep indeed!

For Reference: Here's how I connected #PineCone #RISCV #BL602 @PINE64 to Pine64 RFM90 #LoRa Module (SX1262)

When #BL602 hunts for the next #LoRa Frequency Channel to transmit (Spread Spectrum) ... It listens to the airwaves to check whether the channel is in use ... Let's find out whether BL602 is doing Carrier Sensing correctly 🤔

Based on earlier #LoRa Coverage Testing (with #BL602 and #WisBlock) ... High chance that our Mystery #LoRaWAN Transmitter is at the nearby Subway Station 🤔

Our #BL602 Driver for #LoRa RFM90 Module @ThePine64 is complete! 🎉 I hope to see this in your #PineCone LoRa project real soon 👍

https://github.com/lupyuen/bl_iot_sdk/blob/master/components/3rdparty/lora-sx1262

And now #BL602 #LoRa SX1262 receives LoRa Packets successfully from RAKwireless #WisBlock yay! 🎉

Semtech's Reference Implementation of #LoRa SX1262 Driver is a little odd ... It doesn't process interrupts automatically! Fortunately on #BL602 FreeRTOS we can easily forward the interrupt to the Application Task for processing

RAKwireless #WisBlock receives #LoRa Packets ... From #PineCone #BL602 connected to #Pine64 LoRa Module! 🎉 Now we do the other way ... WisBlock sending LoRa Packets to BL602

Awesome #LoRa Goodies @PINE64 ... Many thanks to RAKwireless 👍

Huge relief because HopeRF RFM90 Datasheet doesn't say that #LoRa 923 MHz is supported for Asia Region ... But we proved that the #Pine64 LoRa Module works at 923 MHz!
