Please be aware that that TinyLoRa doesn’t receive any of the network commands that are sent by TTS so there are some configuration details that will reduce the gateway transmissions - you need to set all eight frequencies so that they repeatedly sent as a setup and ideally tune your data rate for the distance from the server - the stack may still try to send ADR commands but at least your DR will be good for the radio environment.
I haven’t revisited the Pico option of late, there wasn’t a feasible way to reduce sleep power consumption when on battery without too many shenanigans.
However my toolkit of modules has increased so it should be feasible to take this for a spin - if only to benchmark some edge ML libraries on the Pico which, with solar power (a rare event in Bolton), may make the Pico viable with some external timer chip.
ok thanks for the feedback on this plus all the other posts I see you reply to as well ! I’ve got a lot to learn, and I’ll need to invest a lot more time if want to become halfway compentent. …not sure if this tech is for hobbyists like me. Maybe Arduino LMIC/MCCI is a better learning environment?
a rare event in Bolton
… never been there, but I did spend some time around Leeds about 20 years ago . Pretty part of the country - even if it is grey!
This stuff has both a forward and reverse half-life - you get to half-way and then a quarter then an eighth and then a sixteenth but never the end - meanwhile the tech gets more complicated so if you stand still you go in reverse.
It’s for everyone, they just have ranges of success depending on how they apply themselves, it and ask good questions.
To start out, I’d say yes, if only because there is the LMIC-node that is a wrapper to LMIC that will insulate you from some of the finicky details, supports a range of hardware (hint, I’d start with the Adafruit Feather M0 with RFM95) and there is a body of knowledge on here (including the LMIC-node author) to help you get started. Arduino kit also plays nicely with batteries, which is one of the key aspects of LoRa.
The Pico library from Sandeep is an implementation of LoRaMAC-node, the official reference implementation and is somewhat like having your brains beaten out by a gold bar wrapped in lemon, or, as I prefer to call it, a Pan Galactic Gargle Blaster. It is useable but it’s not the shallow end of the pool by any means.
anyhow I have lots of options => my local supplier has M0+RFM95 so I migt pick one up. I was just looking in my supplies bin and I see I have a Rak811 PHat too. I might give this a spin. @Nick, I see you are over at the RAK forums too. Nice to see all the support from you =>
This is directly supported by raw LMIC as well as LMIC-node and has potential for 3+ years battery life.
The Pico+RFM95 experience with LMIC-node will be identical to the Feather on LMIC-node but I’ve not got much less than 900uA on the Pico in sleep mode.
So either is fine for on the desk, but for deployment, it’s all about the power source.
Different sort of beast, same end result - you pipe faux AT commands through a serial port and the module gets on with the heavy lifting. There are attempts to get LMIC with an RFM95 working on the Pi, most of them succeed to some extent, but Raspberry OS is not real time so it can glitch the LMIC timings occasionally.
