I noticed that when pressing the ctrl-d key combination in REPL micropython it stops / blocks displaying the message Cpu Halted. And the only reset option is to physically disconnect the power supply (in the case of m5atom)

@world101 Thanx! After making new topics and setting them to QoS=0, and retain=0, it finally works with many MQTT subscriptions on both M5Stack and M5Stick-C! (1.4.4 and 1.4.5) (PS! Just changing the old topics that had retain back to no retain, did not work, had to make new ones.)
