Burn CC25xx/HM10 firmware using a NodeMCU or Wemos D1 mini.
Flashing CC2530 or CC2531
Use the files provided in folder Bin. The BIN files are already converted and ready to flash with CCLoader
Detailed Zigbee flashing information. Thx @blakadder
Flashing HM10 (CC2541) or CC2540
- Wire the pins:
| Pin Name | Pin# | NodeMCU/Wemos Pin | GPIO# |
|---|---|---|---|
| P2_1 (DEBUG_DATA) | Pin #8 | D5 | GPIO14 |
| P2_2 (DEBUG_CLOCK) | Pin #7 | D2 | GPIO4 |
| RSTB (RESET_N) | Pin #11 | D1 | GPIO5 |
| 3.3V | Pin #12 | 3.3V | |
| GND | Pin #13 | GND |

Use CCLoader.exe to load the CC2541hm10v707.bin firmware via the NodeMCU to the HM-10 with command:
CCLoader_x86_64.exe [Number of the COM port] CC2541hm10v707.bin 0

Troubleshooting
If you're not sure the flash succeeded connect to HM-10 module over serial and issue AT+VERR commands which should show v707.
If you cannot communicate with the HM-10 module even after a successful firmware flash change you serial terminal baudrate to 9600, then issue AT+RENEW command which should reset the module to firmware factory settings and the proper 115200 baudrate.
You can Up- and Downgrade to other firmwares using the Manufacturer upgrade tool.
