I have reset the arduino several times(20 or more), one of them the module started transmiting and now is working again.
I tried with some other modules, switching them off for several minutes, and the problem is the same.

Hi, I'm using mysbootloader with MYScontroller to upload firmware OTA
I've been able to upload several FW's (repeater, temperatures relay, etc.) Everything works fine for several days, but when I switch off the node for some minutes, and then switch on again, the node start requesting firmware in a loop, I'm not able to upload any FW or to reboot the node from MYSController.

These are the messages received in MYSController from the node
