Lastest Issue of Wireless Q Available

Nordic, the manufacturer of the System on a Chip (SoC) in many beacons, has published the latest issue of Wireless Quarter Magazine. It showcases the many uses of Nordic SoCs.

This issue mentions three ‘smart’ products, a smart cricket ball, a smart luggage tag and a smart bike helmet that are effectively beacons or sensor beacons in different form factors.

The IoT will overtake smartphone centric products as Bluetooth LE tech’s main market by 2024

The World’s first dual Arm Cortex-M33 SoC, the new nRF5340 SoC, is also mentioned. This will allow for more CPU intensive applications such as TCP/IP networking and edge processing of data.

There’s also a feature on asset tracking and locating systems valued at $19 billion last year and expected to reach $128.75 billion by 2027, with a Annual Growth Rate (CAGR) of 24.5%.

The Sogo/MokoSmart VILOG car tracking system is featured and is pertinent as we are a distributor for MokoSmart beacons.

New Bluetooth Range Extender

Nordic Semiconductor, the manufacturer of the System on a Chip (SoC) inside most beacons, has announced a new Bluetooth Range Extender the nRF21540.

It’s an electronic component to be used at the SoC output to amplify the signal prior to being sent to the antenna. We expect this to be included in some future long range beacon designs. However, note that it uses more current (115 mA at +20 dBm) so is less suitable for use in coin-cell based battery powered designs.

Our ultra long range beacons already use RF amplifiers but from different component manufacturers. For example the iB003N-PA uses a RFAXIS X2401C chip to achieve up to 300m range. The FSC-BP109 also uses an output amplifier to reach up to 1000m on Android and 4000m on iOS but this beacon requires USB power.

nRF Connect Features

Nordic, the manufacturer of the System on a Chip (SoC) in most beacons, has a new blog post on Five Things You Didn’t Know About Nordic’s Mobile Development Apps. The post mentions less visible features of nRF Connect on iOS and Android. For example, you can get a useful RSSI graph by dragging the screen towards the right from the centre:

nRF Connect is the main app we recommend for testing beacons. iOS recently received a completely new version. nRF Connect also has macros that can speed up testing.

How Power and Advertising Interval Affect Battery Use

Nordic Semiconductor, the manufacturer of the System on a Chip (SoC) in most beacons has a useful online calculator that helps work out the battery current used when advertising or when connected.

You need to set the SoC chip type (see the specification for the beacon you are using), voltage (3v as it’s usually a coin cell), DCDC (usually off), clock (usually external) and tx payload (set to 31 bytes). You can then vary the role (advertising or connected), power and advertising interval to see the affect on the battery current.

Dividing the battery capacity by the current will gives the approximate battery life. The resultant battery life calculation will be a very rough approximation and will be less if the manufacturer has added extra circuitry such as sensors. The online calculator is best used to get an appreciation of how changing parameters or the SoC type affects battery life rather than being a definitive value. For more accurate battery use it’s necessary to measure the actual battery current.

New Wafer Thin Nordic nRF51 SoC

Nordic, the manufacturer of the System on a Chip (SoC) found in most beacons has announced that an ultra thin version will be available from American Semiconductor.

The AS_NRF51 Flex-BLE (pdf) is an ultra-thin version of Nordic’s nRF51822 SoC wafer-level CSP (WL-CSP), employing American Semiconductor’s ‘FleX™ Semiconductor-on-Polymer™’ (FleX SoP) process to reduce package size to approximately 35µm—roughly half the thickness of a human hair.

The largest component of beacons and Bluetooth sensors is usually the battery rather than the SoC. However, the Flex-BLE version will be especially suited to energy harvested and solar solutions where it will be possible to create very thin beacons that can be invisibly manufactured into products or their packaging.

Smart Cycling Helmet

Nordic have news of a new cycling helmet with embedded nRF52 device, also used inside many beacons, that detects acceleration and in conjunction with an app, can send location and crash alerts.

While it’s an interesting and innovative product, most of the work is done by the app. There’s no reason why a generic acceleration sensor beacon couldn’t have been used within the helmet (or elsewhere). However, we guess including anything extra inside a helmet, in a safe manner, poses some challenges.

An insight from this is that there are probably many untapped opportunities for vertical sensor beacon type applications that predominantly make use of apps to provide for much of the functionality.
