Nordic Semiconductor recently highlighted the product in a newsletter because the sensor, which can be part of a Specialized helmet, is based on the Nordic nRF52832 Bluetooth LE SoC.
The ANGi Crash Sensor is described as a “ride tracker, crash detector, and safety beacon”, detecting and reporting potentially dangerous helmet impacts to an accompanying app. Basically, it notifies your specified emergency contacts and sends them your most recent GPS coordinates.
It uses the Bluetooth to launch a pre-configured countdown alert on the partner app, which the rider can always cancel if they prove to be uninjured. Specialized writes:
“Just pair ANGi with a smartphone equipped with the Specialized Ride App. If ANGi detects a crash during a ride, it sends a countdown alert to your phone. If you’re hurt and unable to stop the countdown, the app transmits a text alert and your most recently uploaded GPS coordinates to your emergency contacts.”
In more normal circumstances, it also records your ride and performance data and syncs with apps like STRAVA.
Weighing 10 grams, features include start ride notifications and ride-time alerts, and it has an approximate six months of battery life from a CR2032 coin cell battery. The device has a built-in accelerometer and gyroscope.
“Our patented ANGi sensor calls for help when you can’t. In fact, it’s the first device to protect you before, during, and after a crash.
“What about if you’re out of service coverage? ANGi has a plan for that. Just set your estimated ride time before you head out when you know that your ride will take you out of range. All you need is an active data signal when you start your session. And if you haven’t completed your ride within that time frame, ANGi will send a notification to your contacts with your last uploaded location.”
The ANGi Crash Sensor retails for £40.00 and it’s available for both Android (7 and later) and iPhone (iOS 11, or later).
Why the name ANGI? Apparently it stands for “Angular and G-Force indicator”.
On the Bluetooth angle for the ANGi product, Nordic further expands:
“The nRF52832 SoC has been engineered to minimize power consumption with features such as the 2.4GHz radio’s 5.5mA peak RX/TX currents and a fully-automatic power management system that reduces power consumption by up to 80 percent compared with Nordic’s nRF51 Series SoCs. The result is a Bluetooth LE solution which offers 58 CoreMark/mA, up to twice as power efficient as competing devices.”
“Nordic’s nRF52832 multiprotocol SoC combines a 64MHz, 32-bit Arm Cortex M4F processor with a 2.4GHz multiprotocol radio (supporting Bluetooth 5, ANT, and proprietary 2.4GHz RF protocol software) featuring -96-dB RX sensitivity, with 512kB Flash memory and 64kB RAM. The SoC is supplied with Nordic’s S132 SoftDevice, a Bluetooth 5-certified RF software protocol stack for building advanced Bluetooth LE applications. The S132 SoftDevice features Central, Peripheral, Broadcaster and Observer Bluetooth LE roles, supports up to twenty connections, and enables concurrent role operation.”
