Building #Mynewt OS's Newt Manager with #GoLang on #RaspberryPi 4 was surprisingly easy... Next: Connect Newt Manager via Bluetooth LE to #PineTime Smart Watch @PINE64! https://github.com/apache/mynewt-newtmgr

Studying the #GoLang Newt Manager code from #Mynewt OS... And adapting it for flashing #PineTime Smart Watch @PINE64 https://github.com/apache/mynewt-newtmgr/blob/master/nmxact/xact/image.go

Browsing the #Mynewt OS Newt Manager code... To figure out whether it can flash #PineTime Smart Watch @PINE64 over Bluetooth LE https://github.com/apache/mynewt-newtmgr

Can #Flutter be used to flash #PineTime Smart Watch @PINE64 over #BluetoothLE... From Android and iPhone? 🤔 https://pub.dev/packages/flutter_blue

I'm also doing more with #RaspberryPi during lockdown... Like flashing #PineTime Smart Watch @ThePine64 over Bluetooth... https://www.zdnet.com/article/raspberry-pi-sales-jump-heres-why-the-tiny-computers-in-demand-in-coronavirus-crisis/

Wonder if two persons wearing #PineTime Smart Watches @PINE64 can exchange secrets just by shaking hands... If we ever shake hands again...

So a #PineTime Smart Watch @PINE64 (with built-in Heart Rate Sensor) can be used to detect Mental Stress... Maybe as Lie Detector too? 🤔

Seems feasible to join #PinePhone and #PineTime in a #BluetoothMesh... So PineTime @PINE64 will have mesh access to the internet yay! Just replace Raspberry Pi by PinePhone in this article (and nRF52 by PineTime): https://medium.com/@ly.lee/bluetooth-mesh-with-nrf52-and-apache-mynewt-44823407c471?source=friends_link&sk=ac433fa04e13f75985927c37db1e2b10

Diving deep into #Gadgetbridge... 1️⃣ How to make it talk to #PineTime Smart Watch @PINE64 2️⃣ Will it work on iOS 3️⃣ What about Ubuntu on #PinePhone? https://gadgetbridge.org/

Awesome Updates on #PineTime, #Pinebook, #PinePhone @PINE64 ...

So thrilled that some researchers are using my repo! Update: If you're looking for @NordicTweets #nRF52 Firmware based on @RustLang, @Apache_Mynewt and #NimBLE Bluetooth... Please use this #PineTime Smart Watch @PINE64 version (works for any nRF52) https://github.com/lupyuen/pinetime-rust-mynewt

Great to have Casper onboard the #PineTime Smart Watch Community @ThePine64... Looking forward to the cool new things in #Mynewt OS, #MCUboot, #NimBLE and OTA! 😀

@rafaelcaricio and I are creating #RustLang Bindings for #LittlevGL... So creating fancy Watch Faces and Watch Apps gets easier on #PineTime @PINE64 ! Stay tuned here (apologies my Rust code isn't really idiomatic yet)...

Pondering how to build @RIOT_OS on Windows for #PineTime Smart Watch @PINE64 ... Without MinGW and MSYS 🤔 https://github.com/lupyuen/PineTime-apps

Measuring the power usage of #PineTime Smart Watch @ThePine64...

Static Variables in C can create strange problems... Here's how Rust prevents them! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Some things in C shouldn't be passed via the Stack... Rust prevents that by checking Lifetimes! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Strings are Safer in Rust than in C... Here's why! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

I'm using bloated Bezier Paths too for #RustLang on #PineTime @ThePine64... 🤔
