How to update the firmware of the SMS-Timing Lapo Remote

Hardware needed

To update the firmware of the SMS-Timing lapo remote you need:
 - The remote itself,
 - A PC, 
 - A Micro-USB data cable


Then follow these steps:

1. Download the firmware from
or ask someone from SMS-Timing.

2. Switch off the remote completely, by pressing and holding the C button.

3. Keep the enter key pressed, and briefly press the C button. This will get the remote into the bootloader.

4. Connect the remote with the PC using a Micro-USB data cable.
Be aware that not all USB cables will work!
