I am happy to share with you that I have revived a project that was stuck for years using SlimLora. It uses multiple LoRa Radio nodes with an RFM95 and an ATMega328p on board. These ware cheap boards from China.
With a button and a buzzer, I send messages that are received by a Node-RED instance, which responds on a downlink.
Great fun!
Thanks for the work, and I will follow and contribute when possible.
Happy to help!
Thanks for the message. I think @novag deserves more credits. I still learn from SlimLoRa and I am still discovering bugs. I have some more ideas to implement. But I am not sure I will do them.
I am using SlimLoRa daily on 2 devices. In future probably 10.
I assume its a standard case but where did you get the board support frame? looks neat
Yes, it is a standard ABS housing that I obtained at a flea market for radio amateurs.
The frame is 3D printed, and I designed it myself in SketchUp.
Clever idea, its always been a forever problem the attachment of circuits into generic holed boxes
@pe1mew and now SlimLoRa-0.11.0 runs with 32bit counters. If you transmit every 5’ the rollover would be after 40.000 years, with 16bit counters rollover after 6 months.
I had MIC mismatch after the rollover, so I upgraded to 32bit counters.
Attention: you can’t just upgrade, use the eeprom utility to set the current counter according to LNS, or rejoin.
Good to know. Nice to see that 32 bits is supported now.
Happily for me i do not need to upgrade.
With 2 packets a day and a 16 bit counter my framecounter will be limited to 32767 days, or battery life.
