RadioLib VS arduino-LoRa

I don’t actually think this is true. The flipper uses a CC1101 for sub-ghz and this library looks to have implemented APRS with it. https://github.com/jgromes/RadioLib

I hooked up the radios to some microcontrollers and used this Arduino library along with some other custom code.

Hi Insteon friends, I started to work on this in fear that this day might come and actually got decoding of Insteon rf packets working on an ESP32+CC1101. NorthernMan54 has ported rtl_433 to the ESP32 here: https://github.com/NorthernMan54/rtl_433_ESP, however due to limited memory on the ESP32 I had to merge in changes to some of the methods from https://github.com/obones/rtl_433. All of that said, the range of the CC1101 is really short so probably not a viable option (I know very little about RF, so maybe someone can optimize that?). After that I went down the path of using an RFM69HCW which should have better range and using RadioLib https://github.com/jgromes/RadioLib but ran out of time to dedicate to it. Hopefully someone with more RF knowledge can make this a reality. Happy to upload the code that I used for the CC1101.

Your network, your rules. You can use whatever radio parameters you want, and you can use a frequency not used by popular LoRaWAN networks.TTN does not use great parameters for long range anyway. I use https://github.com/sandeepmistry/arduino-LoRa library its easy enough to use and understand. https://github.com/jgromes/RadioLib is good but a bit more complex to implement.

Radiolib seems to used by mature projects I have looked at - Meshtastic for example. The author added tentative support for Pico, although he doesn't have hardware see here: https://github.com/jgromes/RadioLib/issues/361

I'm simply trying to send a message back and forth. Problem is documentation for these things suck. I found this website https://robotzero.one/heltec-wifi-lora-32/ that is for the 2.0 version. It claims I can use this LORA library ( GitHub - sandeepmistry/arduino-LoRa: An Arduino library for sending and receiving data using LoRa radios. )

I am currently working on a Lora library for the Raspberry Pi Pico. I am using the Pico SDK with C++ and not the Arduino Framework. I'm trying to port the official Lora library for Arduino. Unfortunately, I fail at the Lora.print() function which is used to print the packages, because it is an overloaded function and I can't seem to find the right source code. Unfortunately, the documentation of my Lora chip (SX1276) is not very good, and I don't recognize which values I have to write in which register to actually send a message. This is my current code base.

Yes, you need two LoRa transceivers. There are a bunch of settings including frequency, spreading factor, bandwidth, coding rate, preamble length and sync word that need to match. Read the documentation.

You should send a pull request fixing the documentation for the next person!

You should probably check out LoRA modules. They should be able to achieve >10 km range (under thr right conditions), are reasonably priced and have good library support (e.g. https://github.com/sandeepmistry/arduino-LoRa ). Most of them communicate via SPI or I2C though, so no RX/TX pins.
