That is expected. LED1 turns on only when there's an actual firmware running on the module. Since there's no firmware on the module yet, LED1 won't turn on.

In order to put module in bootloader mode:
1. Turn the module on
2. Press and hold BOOT0 button
3. While holding BOOT0 button press and release RESET button
4. Release BOOT0 button
5. The module should accept firmware flash now
