#PineDio Dongle sends a 64-byte #LoRa Packet ... But the 64-byte Packet doesn't appear in the dmesg Log for CH341 SPI Driver 🤔

https://github.com/lupyuen/lora-sx1262#pinedio-usb-dmesg-log

But #LoRa Messages sent by #PineDio Stack BL604 to RAKwireless WisBlock are not garbled ... Even though PineDio Stack and PineDio Dongle are running the same SX1262 Driver Code! 🤔

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

#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

https://github.com/lupyuen/lora-sx1262/blob/master/src/main.c

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!

https://github.com/lupyuen/lora-sx1262

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

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

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

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

How #Roblox mirrors a Real-World Object thru #LoRa and #TheThingsNetwork

https://lupyuen.github.io/articles/roblox?2#roblox-mirrors-real-life

#TheThingsNetwork exposes an API (HTTP GET) ... To fetch the Sensor Data from our #LoRa Devices

https://github.com/lupyuen/roblox-the-things-network#fetch-sensor-data-from-the-things-network

Yep every byte matters for Low-Power Wireless Networks ... Like #LoRa and #TheThingsNetwork

https://lupyuen.github.io/articles/cbor?2

Remember that #LoRa Messages are super tiny ... We shall encode Sensor Data in CBOR ... And our #Grafana Data Source needs to decode the CBOR Payload

Anyone knows how far a #LoRa Base Station can cover ... In the tropical forests of Thailand? 🙏
