ESP NOW Repeater

Don Recardo asked 1 year ago

Hi I am a member of a model engineers club. Mainly we operate larger scale model trains. I know I can use ESP Now to control the trains as I already found code for that . Our track is a continuous loop of about 440 yards in length but from where we operate you cannot see all of the track as a lot is hidden behind trees which may well attenuate the signal too much . There are places on our site where pretty much all of the track is line of site so my idea was if I could place an ESP board or maybe two in places that can give full view of the track to act as repeaters so if I send a signal its received by a repeater and it relays it ( through the second repeater if necessary ) to the parts of the track that are out of range to me, that way it would  give me full signal coverage of the whole track
So, my two questions are , Can an ESP 32 act as an ESP NOW repeater ?
and if it is possible can some one tell me how to go about it
Thank You
Don

Hi.
Yes.
You just need to save the received message and upon receiving it, send it to the next board.
There is no direct way to do that.
You need to combine both receiver and sender sketches manually based on your specific conditions.
