BLE Extended Advertisement BLE Dongle Support

[Shuhao Dong]

Hello, I am not sure if this is the most appropriate place to ask this question, but any comments are welcomed. I am developming a sensor platform that tries to use extended advertisement and hopefully receive the packets on a Raspberry Pi. I understand that not all BLE radio supports all features introduced by Bluetooth 5.0, at least the one comes with RPi 5 is not supporting extended adv. My question is, does anyone know what usb BLE dongle can be used to receive such advertisement?

Hi,

Extended advertising does not requier anythign specific from the hardware itself (any radio capabel of BLE should be able to do it, so I would assume most BT 5 dongles should be capable of it. But I do not have any specific suggestions.

Hi,

As far as I understand, extended advertisement is not a must in BLE5.0 requirement. Lots of hardware that states to support BLE5.0 does not support extended advertisement at all.

You are right on that. In fact, allmost all new features in BLE since it was originaly includedin Bluetooth 4.0 is optional. But I would be suprised if you can find a fairly new dongle that does not support it (given that it does not requier new hardware features, which makes it different from for instance long range or 2 MBps PHY). Hopefully someone here or elsewhere can recommend a specific dongle, but if not, I would expect you have a high probability of success with just obtaining any fairly recent dongle.
