This looks more like what I was after.

Thanks for your help

Hi,

Do you mean that you want to change the Radio TX power? If you are using one of our devices you would have to make some minor firmware modifications. I can't really provide any help on interfacing with Bluetooth dongles from other companies.

A possible solution would be to use the nRF51 Dongle with pc-ble-driver-js.

Hi, I am already using Bleno which is the broadcast counterpart to Noble.What I am looking for is some help with amending the Broadcast power of the actual Bluetooth device similar to how bccmd does (or should do)

Hi,

I recommend that you take a look at noble which is a BLE central module for node.js.

Hi,

Thanks for your help. I am not particularly wedded to bccmd, is there another approach you would recommend?

I need to have a Raspberry Pi or similar behind the beacon as it is running extra logic in Node.js behind the beacon, cost is not necessarily a major concern, currently.

Hi,

Make sure that you are using a dongle that supports BT 4.1 or later.

I am not familiar with bccmd but according to this page it is made for CSR devices.

If your use case requires a lot of beacons it will quickly get expensive to have every single one attached to a Raspberry Pi. In that case you might want to consider Bluetooth Mesh and having your nodes act as beacons with a single Raspberry Pi Gateway.
