Thanks, herbert! when lick the “Start” button then i reset modue, i’m error.

Are you upgrading our TE-B (development board) or standalone modules?

Thanks! i’m upgrading standalone modules. I think when module upgrading firmware, i pressed the reset so module failed. I followed the instructions here:

Thanks herber.pan so mucht! now, how can i upgrading firmware on my standalone modules, because i still have error “DL_Probe fail!”. i tried again many times.

hi,Son_Goku:
Immediately after you click START, do the following:
step1、Connect the BOOT pin to GND, or short circuit BOOT, and do not disconnect;
step2、Connect the RESET pin to GND, or short circuit RESET. Do not disconnect;
step3、Disconnect the RESET and GND connection;
step4、Disconnect the BOOT and GND connection;

you try again!
