Hi all,
I’ve been tinkering with the MM6108-based Heltec HT-HC01P SPI module, and I was able to successfully bring up HaLow on the Pi Zero 2W. I’ve set it up to enable NAT forwarding, and I’m using a Heltec dongle as a STA. Notably, on 915.5 with 1MHz bandwidth, I’ve been able to achieve 1-3mbps at some incredible range (ie. through several apartment walls over 300-500m) using just a UF.L patch antenna.
In an attempt to help make this wonderful technology by Morse Micro available to the world, I’ve created a repository with instructions and scripts to replicate my work. It’s based on the most recent driver release (1.16.x) for the Linux 6.12 kernel.
For those interested in replicating, the hardest part is honestly the wiring, upon a successful bring up you should be able to get to this point:
A quick speedtest at 923 MHz w/ 2MHz bandwidth - The device is capable of a faster link but I’m interested in optimizing for range so I haven’t tried pushing the limits with a wider bandwidth and higher SPI clock speed.
My next step is to develop a HAT to make it easier to interface with the Pi, and then to package all of this into a user-friendly interface (all of which of course would be open source) to help bring exposure to this fascinating new technology. As a hobbyist whose career is in healthcare, I see so much potential for this technology to improve communication and peoples’ lives, and I really want to help make this more accessible. Many thanks for reading, and for those of you who would like to replicate my setup, let me know if you have any questions!
