Summary
I have a MaPIE LoRa RP2040 microcontroler and I want to be able to send messages to a TTN gateway, i.e., use the MaPIE as a TTN end node. As far as I know, the MaPIE has a RFM98W lora module, but I am not been able to connect it to the TTN network.
Does anyone have used the RFM98W lora module to communicate with a TTN gateway? How can I get my DevEUI, AppEUI, and AppKey to complete the integration?
Any help would be much appreciated!
Hi!
Yes and No. People have created devices using RP2040 + LoRa radio but we don’t communicate with the gateway - its just a media convertor of radio to internet, we communicate with the LoRaWAN Network Server because any number of gateways may pick up your broadcasts and you have no control over which gateways may pick up your broadcasts.
So best to check out the Learn section, linked top of the forum pages - it will save you asking questions that we just respond with “read the Learn section” as it covers all the basics, like where to get EUI’s & Keys (the console will provide them for you).
There are a number of ports of the LoRaWAN stack for RP2040 which no doubt your Google Fu will reveal to you, not much activity on here for RP2040 as it’s sleep current is several orders of magnitude larger than other MCU’s so not battery friendly (months not years) which is one of the points of LoRa.
RadioLib is a potential but its RP2040 setup isn’t “done for you, fall in to your lap” so you’ll need to read the docs. LMIC-node has support but no sleep code but easy enough to sleep the RP2040 for the level that it does.
Where in the world are you? Because the module is for 433MHz LoRaWAN and TTN is mainly 868/915MHz.
Dang, good spot - the back of the board should show which radio is fitted.
