CircuitPython on MaPIE LoRa RP2040

[@DevonsWorkshop]

I’m also working on an rfm95 project in circuit python. If you open up the Adafruit rfm docs or library you’ll see there are a lot more options you can customize. They don’t put many options in the default example. You can specify the baudrate, error correction, syn/ack buffer mode to ensure messages are received and a lot more worth looking into. It’s nice to see someone else with a working text example. Also, no encryption by default so some can eavesdrop on your node if they really want to. If you use it for a mailbox sensor project (most common lora project) it’s recommended to use a large integer instead of simple 1 or 0 to avoid having someone trigger your mailbox or vice versa.

Yes, good note about the additional options! What MCU are you using for your rfm95 project in circuit python? Is it also rp2040?

[@DevonsWorkshop]

Oh I should specify i’m using the Adafruit feather rp2040 and Adafruit feather esp32-s2 with lora featherwings.

Tenho de usar sempre duas placas Lora? Se eu quiser usar um sensor de temperatura e humidade DHT22 e quiser gravar os dados 5 em 5 minutos, numa região remota, como poderei fazer?

[@LeonAnavi]

The example source code in GitHub that I shared is for LoRa P2P between two devices. You can modify and extend it to support DHT22 temperature and humidity sensor. If you need multiple devices consider building or connecting to a LoRaWAN network.

@@LeonAnavi How can I connect it to a LoRaWAN network? Do I need something like a DevEUI, AppEUI, and AppKey for it?
