 In meshcore-cli I went lower-level by implementing channel echoes. When activated (with `/set channel_echoes on`), all the channel messages will be printed on the terminal along with the SNR and path taken. When sending a message, you'll have all the repeats from 0-hop repeaters as echoes, and when a message is received, you should see information about the received message, but also all the instances of the same message that might have reached you from another path.
 
+In the example below, a msg has been sent between two repeaters, 21 and 25. 25 repeated the message and 21 the repeat and both echoes came back to the node with different SNRs.
