Toit
#ESPNow send and receive with dedicated addresses

I try to run the espnow implementation with toit which works fine as broadcasting but when I try to set the address where the data should be send to I revceive an unknown error:
all I changed was setting the address to the service send to be the address of the receiver side.
I also changed the address on the receiver side to be the one from the sender:

ESP_ERR_ESPNOW_NOT_FOUND (0x3069): ESPNOW peer is not found
I am pretty sure I am doing something wrong but what is it? If I am only sending I do not need to add a peer, right?

so I DO have to set the peer even tho I am adding the address already when sending. Not sure if I get this right. As far as I understand there is 2 different modes for espnow: broadcasting - where it will just send data and anyone listening will receive it
and peer-mode where I explicitly send data to a device with a defined address I am adding.
The last mode also works in both directions and I assume setting a peer will make it bidirectional, which is not really needed here... but I guess it also does not hurt

I think you need to add the peer before you do anything with it. (sending or receiving).
floitsch 02/14/2024 01:05 PM
But not 100% certain. Long time since I played with espnow.
theHuanter 02/15/2024 01:57 PM@floitsch did you ever tested the range possible with ESPNow using toit or know any reference for it?
The code says that 1Mbps is default - that should be the lowest setting, right? and therefor the one with max range?(edited)

I try to test it but jaguar lost connection and complained, that way I was not able to run in properly. Can I disable jaguar for that?

I never tested the range.
I don't think the default is the max range.

any other option seems to be higher in value like 2Mbps or 16Mbps

Ok. Maybe we picked the lowest then
