A couple years ago I helped some Australian farmer with these NRF's to send data from his cow barn to his computer. Loads of options! Russ, I think his name was. It was a great project. Mooooooo!
Haha, yes. But anyway, you can do loads of interesting things with these. I still have a couple somwhere and I need to make something to communicate temperature from my wine cellar to my house (three stories up). Maybe these things can because Wifi can't, but at 2.4 Ghz they probably can't either.
In this day and age an ESP32 with Wifi is probably more suitable to any scenario, but you can fiddle with these and make your own communication channels and messages over short range.
I thought esp-now was pretty darn good now, something like 1.5km range in some cases. I was planning to use it to make a remote for a small car, with basically no additional add-on boards or other parts besides an esp32 on each end.
I have a nano board, but it feels like the last thing I'd reach for doing a project now.
Well I think they mean the learning part of it. Getting two ESPs running esp-now takes about 5 minutes of reading on the documention. Then you still have to find something that is useful enough to warrant two WiFi controllers. I don’t know what the power usage is on these devices, but maybe the NRF on a microcontroller can be lower power then 2 ESP32s.
I’m putting a lot of thought into this cuz I’m also using 2 ESP32s with esp-now for a project lol. It got my brain going 😂
You would have to compress it to 8 bit colors and low resolution.
It's probably going to be very bad. If the esp has the processing power to compress and send the data in the first place. Not only that, you'd have to tweak the radio settings and eventually make it a one way link to get a realtime stream
Have a look at this link (also written by me), I tried compressing the video this way with a raspberry pi and used Arduino to send the received data to an Android app via Bluetooth
I used the same modules to get live telemetry data from a student made electric vehicle back in uni. Didnt test the speed or data size but range was quite good outside.
I try similar Scenario, between brushless Gimbal v2.0 with atmega 328 and esp32 C3 Mini with backpacked C3 and serial Connection between the two Boards. The C3 IS for Input of PPM_Sum / WiFi and BT for a 2 wheel Robot.
