Project: RFLink to MQTT using ESP8266 and arduino IDE

I’ve got a strange behavior, I dont know if it’s normal.

Everytime I send a command (and this is working), I’ve got juste after an MQTT entry “online” :

RF/status online
RF/command 10;NewKaku;0110b000;2;ON

RF/status online

as you can see in my mosquito_sub, I have a “\n”, the one I’ve put in home-assistant.
I’m losing one ping packet, so I suppose ESP is rebooting. But don’t know why because I’m using ‘\n’ as asked.

I have the same behavior with a direct publish on mqtt with ‘\n’ :

pi@rpi3-dev:~$ mosquitto_pub -h 127.0.0.1 -t RF/command -m "10;NewKaku;0110b000;2;ON
> "
pi@rpi3-dev:~$
