I am going to flash GR5515GGBD over BLE OTA.
First, I flashed the bootloader and then using GRToolBox, updated the App Firmware. It often works well, but in some case, there is some fault.
Upgrade complete message was popped up but I couldn't find device in scan area of GRToolBox.
Normally, in case of upgrade failure, bootloader is run, but in some case, chip is halted and I couldn't find any device.
Could you let me know the reason ?

Could you use JLINK to debug and identify where it gets stuck?
Open WeChat, use "Scan" to follow.
