Android nRF Connect - proper indication of Coded PHY support

[Lukáš]

Hi, we just found out a bug in nRF Connect for Android indicates that the phone Sony Xperia L4 supports Coded PHY. Unfortunately, when we try to run Bluetooth: Central Heart Rate Monitor with Coded PHY sample, the advertisements on this phone cannot be seen. When we use other phones (e.g. Samsung Galaxy S20 or OnePlus 8T), they can both show advertisements in nRF Connect from that sample. What could be the possible issue? I found this ticket on DevZone but I don't know if it is relevant.

This is a screenshot from Sony Xperia L4 indicating that Coded PHY is supported:

 

Advertising extensions work, but on 1M LE PHY, not on Coded one.

Hi Hung Bui,

I am using Realme 3 Pro (Model: RMX1851). Through nRF Connect Apps I can see my phone support all the LE features, I can scan Coded PHY advertising packet too. However I cannot establish connection with my peripheral (nrf52840) when it is advertising in Coded PHY, I can only scan them. I did look into the link to the Pixel 4 discussion, the problem is similar but not quite the same as my phone can scan the Coded PHY advertising. 

I just want to know if there is known issues like phone that support advertising and scanning in Coded PHY but cannot establish connection with Coded PHY? It has no problem connecting to the peripheral in Extended 1M PHY.

Hi Gary, 

Could you tell how you advertise with Coded PHY ? Did you use extended advertising ? 
Have you tried to establish the connection in 1M PHY and then request to switch to CODED PHY ? 
We currently don't have a full overview of which phones support CODED PHY.
