Re: ESP NOW how improve distance transmission?
Hi
Recompile is too complicated...
I'm in searching in function for set power transmission or something similar to this.
Why LR is not enabled in Arduino???

Re: ESP NOW how improve distance transmission?
Hi
I would improve if possible distance transmission
I'm use this example:
https://espressif-docs.readthedocs-host ... spnow.html
Can I activate LR MODE in that example?
Thanks

From your link:
The Espressif-specific ESP-NOW protocol and Long Range mode, which supports up to 1 km of data traffic

ESP NOW how improve distance transmission?
Hi
After some test I have notice that distance transmission is not 1km as declared but about 200m.
There is some setting that I can do for mprove distance?

How measure RSSI on transmitter from receiver device?
Hi
I should implement many TX to one RX.
I would know RSSI signal of every TX device.
How do it?
I not see any rssi function in esp_now.h file
Thanks
