Maker X Bluetooth module cant load Firmware.??

[jaykup]

Based on the screenshot it appears as though you updated the firmware on the ST-LINK not on the bluetooth module?

These are the steps I’ve followed to load the firmware onto bluetooth modules in the past

@Morpheus

Download these:

• OpenOCD Windows Programmer: https://gnutoolchains.com/arm-eabi/openocd/
• STLink V2 drivers: https://www.st.com/en/development-tools/stsw-link009.html
• Vedders NRF51822 github repo: https://github.com/vedderb/nrf51_vesc

@Morpheus

Steps:

1. Download needed files.

2. Install STLink drivers.

3. Unzip the OpenOCD files & Vedders NRF51 repo.

4. Copy “openocd.cfg” from the NRF51 repo to the OpenOCD “bin” directory (same dir as openocd.exe)

5. Copy the relevant nrf51 hex from the NRF51 repo (under “nrf51_vesc-master\build_all” dir) to the OpenOCD “bin” directory. For me I used “nrf51_vesc_ble_16k_16m_rx11_tx9_led3.bin” as that matched the NRF module I bought (link below).

6. Wire up the STLinkV2 to the NRF51 module; see this for pin assignment:
   

7. Open up a Command Prompt window and browse to the OpenOCD bin folder (or type cmd.exe into the address bar of Windows Explorer if you are already in that folder to open a Cmd prompt already at that folder).

8. Run this command (Change the name of the .bin file to whichever firmware you are using:
   openocd -f openocd.cfg -c “init” -c “halt” -c “nrf51 mass_erase” -c “program nrf51_vesc_ble_16k_16m_rx11_tx9_led3.bin verify reset exit”
   a. You should see an output something like this:

Hopefully @YUTW123 can let you know which firmware version to use
