Signal strength

[PerRieland]

Is it possible to get signal strength from the gateway and node/controller respectively? I am interested in knowing if the wireless signal strength is strong enough between the gateway and nodes/controller. On WiFi, ESPNOW and Lora.

I tested FDRS via ESPnow using ESP32 Dev Boards over a distance of about 70 meters in free sight without problems. The gateway was inside the house. The node in the garden. Also I tested out of a car parking in front of the house to the gateway. It works also perfectly.

I have good results using Lora. But most of the controllers are about 0,5 m. in the ground. So it's hard to estimate if the wireless connection will be good. Sometimes the range depends on if the ground is wed or dry.
Monitor the signal strength would help me a lot in this situation.
I'm unsure how to get the signal strength from FDRS.
Any clues?

There's no signal strength indication built-in to FDRS currently. Both ESP-NOW and LoRa (and WiFi) do have the ability to access packet RSSI though, so you could maybe/probably work out a way to use it in your own code.
FDRS does have a ping function, which isn't exactly what you're looking for, but worth noting.

For measuring signal like this I'll usually just make a new pair of simple, non-FDRS sketches that output the data I'm looking for via terminal or OLED display. My FDRS_LoRa_Test repo actually shows the RSSI on the recieve sketch already, so that's where i would start.
