Unable to pair

[Tomáš Mengler]

I have problem. I'm unable to pair devices. They know about each other and tries to connect but pairing always fails.

esp8266 as gateway
arduino uno as node

Hi @Tomáš-Mengler, welcome to the forum.

The gateway sends a reply (to the node's find parent request) but the reply is not heard by the node.

The most common reason is insufficiently stable power. What capacitor(s) are you using, and how are they connected?

If you haven't already, see https://forum.mysensors.org/topic/666/read-this-first-it-could-save-you-a-lot-of-time/ for the most common problem and how to troubleshoot them efficiently.

@mfalkvidd I added 100uF electrolitic capacitor but same problem

Ok, no help here.
