So I made my customized application. serial port always on --- this works..

a command to turning on/off advertising AT+ADV+0/1 (off/on)

a command to set the eddystone id. AT+ID=10+6 chars

but the normal commands don't respond every time..

AT AT+GMM

here is AT command

Status line(s) changed: CTS: off
AT

so I want to change something, but I can't get back into upload mode

hold Btn 2, click Btn 1

oops.. I disabled the button handler..

is there a way, hold reset on power on?
