Nrf52840 central / peripheral on different phy

[Sebastien DRI]

Hi Folks,

I am currently working on a BLE configuration composed of two NRF52840 chips. One is configured as central and the other as peripheral and use coded phy (long range).

I want the central to be able to manage simultaneously another connection with mobile device.

Does the central can be configured to support a multilink configuration with the following properties :

- connection to 1 peripheral using coded phy

- connection to another peripheral using 1MBPS phy

If yes, could you please give code sample illustrating this configuration?

Thank you for your answers.

The best

Hi

I'm sorry for the late reply, but Susheel is out of office for the time being, and we're only now getting to his backlog.

Regarding the timeslicing, yes you will need to split the time between the two PHYs, as the nRF52840 only has one radio, and will only be able to communicate on one PHY at a time. You will have to use a timer to let the device alternate PHYs so that it can scan/maintain the connections on both peripheral devices.

There is no specific scanning configuration that does this already, so you'll have to implement this yourself I'm afraid.

Best regards,

Simon
