Cell phone compatibility with BLE5 optional features

[jonri]

I'm looking at the feasibility of using extended and/or periodic advertisements from an NRF52 to be received by a cell phone.  I've used nRF Connect on a couple slightly older phones to see whether these are supported (under Device Info, and both were No).  But without actually having access to one of every phone in existence I'm having a hard time finding any information on what phones (if any) support these features.  Are there any resources out there that might have this information?

Hi

Unfortunately, there is very limited support for BLE Coded PHY (long-range)/Extended advertising for mobile phones as of yet. I found this blog that includes a brief list of mobile phones that support these optional Bluetooth 5 features. Also, most of the newer high-end phones generally support these features.

On a personal level, I can add that the Nokia 8.1 supports LE 2M, but not Coded PHY or Extended Advertising. Also, keep in mind that to support Coded PHY, a phone also needs to support Extended advertising, as Coded PHY relies on Extended advertising to work.

Best regards,

Simon
