Anyone have any interest or experience with proximity based BLE iBeacons/Sensors? Answered

Hi All,

I'm semi-tech. & new to the community but figured I'd reach out, so please bear with me as I describe the following ask.

Since last yr. I've been on the hunt for a small iOT sensor that based upon close proximity can be identified & actived via BLE without an attached app. Thought an Eddystone may work but purchased a few nRF51822 semiconductors but haven't tested them as yet & not sure if it's even the proper solution. I would need to program this beacon/sensor to launch a website, video on nearby cellphones. NFC works perfect but is extremely limited to only a 5cm range & requires an NFC capable device.

I was told to try: "Perhaps the Raspberry Pi 3 Model B+ could work since it supports BLE and also has WiFi:


But I'll need something much smaller [see attached] & less costly per unit. I'm envisioning something no larger than a quarter & powered possibly by a watch battery. Do you think the nrf would suffice?

Any suggestions I'm super open as well as just ideation. Thx in advance.
