LD2413 does not respond after parameter change

halt

Hello,
after sending a wrong timing with command 0x71 to LD2413, it stopped responding. Even if I remove the power supply. Now nothing is sent out from the TX line.
best regards.

Restart the module, if it is still no response, restore the factory settings.

I found the RST line on a capacitor and indeed it is resetting. I get a first reply from the chip ("In BootLoader!In APP0"), but then nothing is sent out.
