Establish connection between “LE Coded PHY” Central and 1Mbps Peripheral

[beemavishnu]

Hello,

 

I am using nRF52840, SDK_16.0.0, S140 SoftDevice and Segger 4.16 for flashing the image. I am using ‘ble_app_blinky’.

 I have few queries on “LE Coded PHY”, 2Mbps & 1Mbps combinations.

 

1) If my Peripheral is “LE Coded PHY”, then my Central should be in “LE Coded PHY” to receive the packet. Is this assumption correct ?

 

2) I have gone through few documents and it is mentioned as below

a) If my Central is “LE Coded PHY”, whether it can receive Advertisement packets from Peripheral with 1Mbps.

b) If my Peripheral with 1Mbps tries to connect to Central with “LE Coded PHY”, once connection established, whether Central can change to 1Mbps dynamically.

 

My use case is, I have a Central with “LE Coded PHY” and Peripherals where few are with “LE Coded PHY” and few are with 1Mbps. Always my central will connect only one peripheral at a time. So in this case whether Central with “LE Coded PHY” can establish connection to 1Mbps Peripheral.

 

Thanks & Regards

Hi Simon,

In the long-range blog, both boards are switched from 1Mbps to Coded PHY.

Whereas in my scenario, whether Central can scan both 1Mbps and Coded PHY advertisement packets in primary channels parallel. I mean, during scanning, whether Central can switch between Coded PHY and 1Mbps and scan both 1Mbps and Coded PHY advertisement packets at a time ?

I am trying to understand below statement from my previous snapshot.

"This means that a central must use the 1M PHY or coded PHY when initially searching for peripherals that are sending out advertising packets."

Thanks & Regards
