It looks like the same company who make the ID107 HR have brought out a new product called and ID107 Plus, which uses the better nRF52832 MCU I ordered 2 of these from AliExpress and they arrived a few days ago. However at the moment I can’t work out the best way to open the device to look inside. https://www.aliexpress.com/item/100-Original-Makibes-ID107-Plus-Smart-Bracelet-BT4-0-Heart-Rate-Monitor-Smartband-Pulse-Sports-Fitness/32809803432.html?spm=2114.13010608.0.0.RsxZli   I’ve also contacted the company via an Alibaba PM to confirm if this … Read More

Arduino on the ID100HR fitness tracker

posted in: BLE, Bluetooth, nRF51822 | 20

Some time ago…, Goran Mahovlic commented about how he was trying to run Arduino on an IDo 003, fitness tracker / smart watch which uses the nRF51822. As I’ve been interested in smart watches for some time, I thought I’d buy the same watch, and join in the fun. Unfortunately the first watch I bought didn’t contain an nRF51822 (see my other post about nRF51 based smart watches), so I ordered 2 more of … Read More

nRF51822 based fitness trackers

posted in: Arduino, BLE, Bluetooth | 26

As regular readers of my blog will know I’m an ardent fan of the Nordic nRF51 (and nRF52) series of Bluetooth Low Energy MCU’s. So when I found out that a number of fitness tracker / smart watches, used the nRF51822 and could be easily opened and reprogrammed I was very interested and ordered 2 of them to try. Unfortunately soon after I ordered them, it became clear that the model I had ordered … Read More

Reprogramming the Dash Robotics Kamigami – Part 1

As regular readers will know, I’m a fan of the Nordic nRF51822 Bluetooth MCU, as it can be programmed developed using Open Source tools. So when I saw the Dash Robotics Kamigami at Bay Area Maker Faire in May, and spoke to their hardware engineer Dwight Springthorpe, who confirmed that this innovative educational toy used the nRF51822, I took the plunge and bought one on the spot – at the special show price 😉 … Read More

Arduino on the nRF51822 Bluetooth Low Energy microcontroller

Update May 2018   The articles about programming the nRF51xxx devices are now 3 years old and are only of use for historic reference. Please see the work done by Sandeep Mistry https://github.com/sandeepmistry/arduino-nRF5 for the current status of Arduino development on these devices   Original post… This is the first in a series of posts about programming the Nordic Semiconductors nRF51822 Bluetooth low energy micro-controller using the Arduino IDE. The post is a big … Read More
