#PineDio USB Dongle sends #LoRa Packet to RAKwireless WisBlock ... But received packet is consistently garbled ... As reported by @JF 🤔

I haven't figured how to control GPIO with CH341, so here are 2 Quick Hacks: 1️⃣ Need to reset #PineDio Dongle? Just unplug it ... 2️⃣ Checking for busy state? Just wait 10 millisecs between SX1262 requests

#PineDio USB Dongle @PINE64 transmits a #LoRa Packet ... Which appears as a LoRa Chirp on Airspy SDR! 🎉

Let's transmit a #LoRa Message on #PineDio USB Dongle with these settings ... Connected to Pinebook Pro

Oops just discovered that the new Semtech Reference Driver doesn't support LoRaWAN ... So we switched to the older #LoRa SX1262 Driver ... Exact same driver used by BL602!

Our #PineDio USB Driver returns the exact same Register Values ... As BL602 with LoRa #SX1262! 🎉

Yep our #PineDio USB Driver returns some Register Values for #LoRa SX1262! 🎉

Let's do a simple test of our #PineDio USB Driver ... Read some SX1262 Registers over SPI

https://github.com/lupyuen/pinedio_usb_sx126x_driver/blob/master/src/main.c#L31-L46

Semtech's #LoRa SX1262 Driver requires an SPI HAL ... Here's how we do it with CH341 SPI

https://github.com/lupyuen/pinedio_usb_sx126x_driver/blob/master/src/main.c#L101-L138

Here's how we open the CH341 SPI Port ... And transfer SPI data to #LoRa SX1262

https://github.com/lupyuen/pinedio_usb_sx126x_driver/blob/master/src/main.c

Took me a while to figure out how to build the CH341 SPI Driver with DKMS and Kernel Headers ... Yep it works on Pinebook Pro Manjaro! 🎉

https://github.com/lupyuen/pinedio_usb_sx126x_driver

We'll build our #PineDio USB #LoRa Driver based on Semtech's Reference Driver for SX1262

https://github.com/Lora-net/sx126x_driver

Let's make a Linux Driver for #PineDio USB #LoRa Adapter @PINE64
