Ranging LoRa2021F33-2G4

[vadimbrottsman]

I want to measure the distance between chips on a LoRa2021F33-2G4 chip on an ESP32S3 chip (between the master and left). Has anyone done something similar? I'm also interested in the pinout of the contacts between them.

I've done ranging previously on SX1280 - on LR2021 I haven't done it, and while the chip itself does support this feature, it has not yet been integrated into RadioLib since there's just not been any demand for it, so it is quite low on the prioritites.

I'm also interested in the pinout of the contacts between them.

Not sure what exactly you mean by that, the connections are always the same regardless of whether you are doing ranging or LoRa communication - you have to connect power, SPI, BUSY and interrupt pins.

Partially vibe coded micropython script i have used with the nicerf lr2021 module (not the 2W version you have so I dont know if any changes are required). Maybe it can help you get started.
