Preview of the next version of Pinetime-JF : integration of the motion sensor and step counter in a nice chart !

Thanks to @atc1441 for his precious help on the implementation of the motion sensor!


Using my NRF52-DK board along with NRF Sniffer and to debug connectivity issues between Android and @PINE64 .

Just 1 hour ago, I totally ignored this was possible!

This is so satisfying : connecting and sending notifications from to !!!

: video looks better when the brightness is set to low on the pinetime :D

I've just released version 0.6.0 of Pinetime-JF. The big feature of this release is over , using and . Thanks to @lupyuen for its hard work on integrating MCUBoot into a firmware for @PINE64 !

We did it! Here is a little demo of update over for @PINE64 . This video shows @lupyuen based bootloader, Pinetime-JF beeing updated by a new version of the firmware and then by @lupyuen firmware. The video is a bit long, but... Enjoy!

Because everyone love progress bars, here is my OTA firmware transfert for @PINE64 with a new screen with a !

PS : the video has been accelerated

One step at a time to OTA firmware update in @PINE64 : The implementation of the DFU protocol (using BLE stack)!

Now that I can receive a new firmware via BLE, I need to figure out how to store it on the external flash, and maybe swap it with .

Trying on NRF52832 : Run first image that prints "AAA", upload a new image that prints "BBB", reset and run MCUBoot again, and see that the new image has been started!

This is part of my researches for a bootloader for @PINE64 !

@PINE64 now supports BLE notifications!

Release 0.4.0 brings BLE notifications, nice icons, brightness and sysinfo apps and bugfixes!

Here is the changelog :

Any contribution to improve the UI is more than welcome. Next step : OTA!

LPT : forget about the bad news and work on a fun project like @PINE64 .

Here's my latest achievement : time synchronization and BLE notification from a Linux computer to the Pinetime.

This is the beginning of a Linux companion app for the Pinetime, yay!

Tasting of 'La Jean-Frost', my second beer fermented thanks to JFBrew, my DIY beer fermentation chamber based on !

Sticker by my lovely fiancee <3

It's a barleywine, 7.9% alcohol and... it taste really good!

How to change a weakness (slow refresh rate) into a nice feature : implement a nice scroll transition when the screen needs to be fully refreshed!

Hardware vertical scroll + LittleVGL + @PINE64 community = 👍

Credits to for the idea!

Version 0.3.0 of my C++/#FreeRTOS/#LittleVGL firmware for @PINE64 is available!

The major change is the integration of LittleVGL as UI lib. It contains 5 demo apps showing the capabilities of the firmware and of the device!

Release Note :

Testing widgets (button matrix, gauge, meter) on my firmware !

Also notice that the refresh time has been improved thanks to many optimizations on the SPI driver and LVGL integration!

And I've found a way to disable auto-focus on my camera! Yay!


Debug and timing analysis of my firmware using my brand new Saleae Logic 8 !

This pretty little thing will be very helpful to improve battery life, timings, performances and debugging!


Infinite scrolling rainbow on using hardware vertical scrolling.

The colors are generated dynamically, instead of just looping the same buffer over and over again.
It requires only a single line buffer!
