How to flash Seeed Wio-WM1110 Dev Kit with Meshtastic

The Seeed Wio-WM1110 Dev Kit is an nRF52840-based LoRa® transceiver with built-in GPS, Temperature/Humidity sensor and supports solar and battery power. Unfortunately, unlike many Meshtastic devices, this board cannot be flashed using USB. Instead, you require an external device that can connect via SWDIO. Luckily, if you have a Raspberry Pi around this is surprisingly straightforward. 1. Set up Wiring Connect GPIO pin 11 on your Raspbery Pi to the CLK pin on the Wio-WM1110. Connect GPIO pin 8 on your Raspbery Pi to the DIO pin on the Wio-WM1110. Ensure you get the GPIO numbers correct. Plug in your Raspberry Pi to USB power. Plug in the Wio-WM1110 to USB for power. 2. Install OpenOCD OpenOCD is the program we'll use for communicating with the Wio-WM1110. Install it on your Raspberry Pi. $ sudo apt update $ sudo apt install libtool autoconf automake texinfo telnet gdb-multiarch git $ git clone git://repo.or.cz/openocd.git $ cd openocd/ $ ./bootstrap $ ./configure --enable-bcm2835...

The Story of LLRP2HRP - Part 2

So, this brash American dude who ran a relay race event decided to go fancy. None of this using phones to manually scan NFC chips for race timing. He was going to have chips in bibs. He convinced another organisation that also ran races to chip in some funding ... and then went online. He found an RFID reader system. The kind of ground mats that you run over, that connects to a box that goes beep. It was from China. It was insanely cheap. Like fall-off-the-back-of-a-truck cheap. It was delivered, hardware checks out. It came with no software. Last time , we'd figured out that it also provided RFID tag information using a proprietary binary protocol and were trying to lock down exactly what that was. It was one of the most arduous Google sessions I've had for a while. Trawling the entire web for some document or code that probably only existed inside an office in Shenzhen. But I found something! It was amazing, because of the source, and how perfectly it fit my n...
