Advertise battery level in beacon advertising packet

1. I am using the ble_app_beacon example as the starting point for my project. I am working on a project where a number of beacons will advertise its identity and battery level to the central node. My question is : how to modify the beacon advertising packet to contain battery level information along with the unique device ID? Which portion of the code in this example shall I modify? I am trying to optimize this device for optimal battery performance as well.
2. Also how can I read this advertising packet in the central node? What is the relevant example in the SDK to achieve this. I want these nodes to be read as soon as they are detected and then sent over to another module via UART?
3. I have read somewhere that beacon is public and hence there are security issues involved. Can I instead use connectionless advertising and what is the relevant example in the SDK to achieve this?. I see most of the ble example assumes connection between the peripheral and central devices but this feature is irrelevant to my project.

I am using SDK 17.

I would highly appreciate any help or suggestions. Thank you so much.

I have one nrf52840, which I have configured to transmit beacons using ble_app_eddystone example code. I have another nrf52840 and I have tried above code in it to scan the beacons but I am unable to see any beacon data on debug terminal. Vidar Berg ysuleiman can you please guide me for checking the scanned beacons data?

Thank you

Bhakti.

Hello,

I made it to scan for the nordic beacon implemented in the Beacon Transmitter Sample Application. The Eddystone Beacon uses an entirely different beacon format and will not work with this code.

Thank you Vidar Berg for quick reply. I needed receiver for eddystone beacons. I tried making changes (removed manufacture code filter and all) in receiver code to receive eddystone beacons but as you said it has completely different frame format and only working with Beacon Transmitter Sample Application. Can I get the receiver code to receive all type of beacons or eddystone beacons?

We do not have a Central/Observer implementation for Eddystone, unfortunately. Creating a receiver which can work with all the Eddystone frame formats will require a bit more effort than just a regular beacon scanner.
