Anyone had any experiences with the Adafruit TinyLoRa LoRaWAN library ? I know its ABP only. I just converted a working GPS tracker program from the matthijskooijman LMIC library across to TinyLoRa. Its working and I get the GPS co-ordinates in the Application console OK. TinyLoRa seems to do rat…

[image] LoRaTracker: Any known issues with TinyLoRa ? The most obvious would be that it appears to be transmit-only, while LoRaWAN is really designed to be “transmit mostly”. Given you can only use confirmed traffic on TTN very sparingly as downlinks are so expensive for the network, that pe…

Thanks for the comments. Yes, I guess the temptation is to set it to SF12 just in case, and for a GPS tracker in particular therin lies a major problem. At SF7 a location packet has an air time of circa 67mS, so under the fair use policy you could send 486 packets a day or a packet every 3 minutes…

The problem with fixing on SF7 is that unless in a dense GW population many of the addition Tx’s you are allowed would never be heard given inherently shorter range and a tracker that cant be tracked is a bit useless! :wink: Compromise at SF9 or 10? Issue then is if lots in area doing same for simil…

Edit: (Not TinyLoRa but relevant to your list) If you want OTAA you can try this implementation . Stripped back with one radio driver and no debug messages it will fit into 23678B flash and 720B ram. A sketch with one radio, debug messages, sleep, and a DHT sensor occupies 27742B flash and 734B ra…

Personally, I think you want ADR. I’m relatively unconvinced on the merits of OTAA, especially in a situation where you as the end user are building the firmware. It might make more sense for a pre-manufactured, pre-programmed product that doesn’t know at manufacturing time who will be using it or…

[image] LoRaTracker: Any known issues with TinyLoRa ? I had a quick review. It’s bare bones, are lot of lines are just for the AES implementation. be aware channel randomisation is determined by the MIC and that channels are allowed to repeat no timing is performed by the library (duty cycl…

[image] LoRaTracker: Any known issues with TinyLoRa ? Does not support SX1272, not an issue as such, as the library was written for RFM95/96.

Hi all, Maybe RIOT-OS support of LoRaWAN could be interesting for you? [image] RIOT-OS/RIOT RIOT - The friendly OS for IoT. Contribute to RIOT-OS/RIOT development by creating an account on GitHub. It has out of the box support for LoRaWAN (see this example a…

One application to which TinyLoRa is suited is TTN Mapper. The recommendation for that is to use a single spreading factor, SF7, which is a close match to TinyLoRa’s capabilities. A TTN mapper with GPS and OLED to show the mapped location uses 62% of Flash and 49% of RAM on a humble Arduino Pro Min…
