Sky 201 Sensor Data in Advertising Data

One of our customers had kindly sent in some information regarding the Sky 201 sensor beacon. The manufacturer information only mentions connecting via GATT to get the acceleration, humidity and temperature data. However, our customer has discovered it’s also available in the extended advertising data as service data:

The left hand side is Nordic nRF connect showing the advertising data. The right had side is the data shown (presumably via GATT) when the configuration app is connected.

More Sky Beacons Available

We have had some stocks come in from Sky and we now have three extra beacons available.

The first is a variant of the Forecum 200 that’s mounted in a wristband.


We also have a new rechargeable, wearable beacon, the HV104 that recharges via USB:


Finally, we have an unusual beacon, the HF300 in that it can be powered by USB or AA batteries. We believe the intention is that it is usually powered by the USB and the AA batteries act as a backup in case of loss of USB power:


Sky Forecum 201 Longer Range Than Expected

In our beacon testing, we occasionally come across a beacon that behaves better than the manufacturer’s specification. The Forecum 201 is one such beacon that while having a specified range of up to 100m, actually achieved a range of 108m at normal power (0dBm) and 190m at full power (+4dBm). This is unusual because we have found that most manufacturers tend under-deliver rather than over-deliver when it comes to matching the quoted range in real-life situations

We were curious as to whether this was at the expense of battery use and were pleasantly surprised when our battery power tests showed that a new battery will last 1.8 years at 1s transmission and 0db power.


The Forecum 201 supports both iBeacon and Eddystone (URL and UID) and is available in both sensor (humidity, temperature, acceleration) and non-sensor versions.
