Hello, I wonder if anyone has successfully hooked up 3 esp's to same uart (uart0) using Rx->Tx and Tx->Rx of all three mcus at the same time? I have two set up with Serial comm (one using ESPNow and the other as access point/webpage), can more mcu's be added using the same uart. I don't need all three hooked together, just two hooked to a common one. Thanks!

I think softwareserial library must be user for such cases.

I did try hooking three chips together with Serial, from one to the two others (didn't hook all three together symmetrically, one was feeding the other two) and this worked fine.
