I have 12 ESP clients with ESP Now
I want to connect it to 12 ESP Now Listeners/Slaves
These ESP listeners are soldered on one PCB, at about 15mm distance from each others.
Problem 1: I came to know that multiple ESP listener modules can't be mounted on one PCB very close to each other,
All 12 clients can send data at same time to to their receiver end.
Problem 2: But receiver end can't receive data transmitted at same time from 12 devices because in that case transmission collusion will happen and non of receiver will be able to receive data.
Still not sure why you would want to do this.
Can you tell us:
- how much data are you sending
- how often are you sending it
Why do the clients have to send data to a unique receiver? Why can't you simply aggregate them together and have them all send data to one place? If you use the mesh network library I mentioned earlier, then the data will flow between them over the mesh protocol, and then one of them can send it on to a server via regular TCP/IP.
The other thing is that there will always be some latency between devices so you're not going to get the sort of clashes you're talking about. Even if you run with the out of the box TCP/IP Wifi networking configuration, you can have up to 5 clients on one ESP device
