Another tip if you choose the sonoff stick. Currently only the [sonoff branch of the flash python script](https://github.com/JelmerT/cc2538-bsl/tree/feature/ITead_Sonoff_Zigbee-delay) supports flashing the firmware without disassembling the stick to get access to the flash button:

```auto
python.exe cc2538-bsl.py -p COM3 -evw --bootloader-sonoff-usb latestFirmware.hex

```
