A more negative number indicates the beacon is further away. It’s expressed in dBm and is always negative. The MAC address uniquely identifies the device.ĭevices that scan for beacons will experience a signal strength (RSSI) that varies depending on the distance to the beacon. All devices have the MAC address and a Received Signal Strength Indicator (RSSI). Below you can see an iBeacon that has been tapped on to show extra information. In the above screenshot you can see two devices.

Due to over-zealous efforts by Apple to hide identities, it’s not possible for iOS scanning applications to see advertising iBeacon (UUID, major and minor) information nor the Bluetooth MAC address.

It’s important you use the Android version of nRF Connect. nRF Connect is intelligent in that it works out the kind of beacon and displays the appropriate type of information. Nordic nRF Connect detects all beacons and indeed all Bluetooth LE devices, irrespective of the SoC manufacturer because it just looks for standard Bluetooth advertising. The best scanning app is Nordic nRF Connect that’s written by the manufacturer of the System on a Chip (SoC) in most beacons. Other times, you might want to know a beacon’s MAC address. It’s also sometimes necessary to differentiate between beacons, based on their signal strength, so you know you are setting up the correct beacon. It’s often the case you need to know if a beacon is working and advertising the correct information. The other end plugs into a nRF52 DK that has a debug out header at the top right: A jig with pogo pins (pins with springs) can be used to help programming larger number of devices: Jig in use at BeaconZone The PCB holes mentioned in part 1 are used to program the beacon in the circuit.

There are two ways of programming, either pre-programming the SoC with production code before mounting using socket programming or programming the SoC after mounting in the circuit. Most Nordic code examples in the nRF52 SDK now include a SEGGER Embedded Studio project file. Most development now uses SEGGER Embedded Studio because Nordic have licensed it to allow Nordic developers to use free of charge. Use of a softdevice allows developers to concentrate on their own high level product functionality rather than lower level complexities.īeacon manufacturers or 3rd party developers such as ourselves create a program using either SEGGER Embedded Studio (SES), MDK-ARM Keil µVision, GNU/GCC or IAR Workbench. It provides eight connections with an Observer and a Broadcaster role all running concurrently. A SoftDevice is a precompiled and linked binary library implementing a wireless protocol, Bluetooth in our case.įor the nRF52, the S132 SoftDevice provides a qualified Bluetooth® 5 low energy (BLE) Central and Peripheral protocol stack solution. To prevent every product vendor using the SoC having to write the Bluetooth part themselves, Nordic supply what’s called a SoftDevice. It also has to pass tests by the Bluetooth SIG, called qualification. The code required to implement Bluetooth, called the Bluetooth stack, is very complex.

In this part we take a look at the System on a Chip (SoC) software and programming for the Nordic nRF range found in the majority of beacons.ĭespite the small size and memory, a typical beacon contains lots of code written in the c programming language.

This is part 3 of a 3 part series that explains what’s inside a beacon. View our ultra long range beacons Author Support Posted on FebruFebruCategories faq, iB003N, Nordic, Power, Range, SoC Inside a Beacon – Part 3 – Programming the SoC You can see that this beacon is primarily designed for long distance and there’s no need to change the SoC power from the default 0dBm = 20dBm.

That’s just over 3x the power (3dBm change is a doubling of power) of a normal beacon. Even at a low power setting, -10dbm, the amplified output is 10dBm which is relatively high compared to the nominal 0dBm for most beacons. There’s no difference whether you set to 0dBm or 4dBm, the output will be 20dBm. The resultant change in output is: SoC SettingĢ0dBm is the maximum allowable output for class 1 Bluetooth. In the case of the iB003N-PA, the RFAXIS X2401C instead receives the signal, amplifies it and sends it to the antenna. When you use the manufacturer app to change the power output by a beacon, you are changing the power output by the Nordic nRF51 System on a Chip (SoC) that is usually fed to the antenna.
