nRF52840 How does a normal ble device connect to 52840 in long range advertising mode

nRF52840 in long range advertising mode, how does 52832 connect to  to it, or a normal ble device connect to it?

Hi,

Given that you're using HW that supports the Coded Phy ( nRF52832 doesn't!), there shouldn't be that much difference from sending a connection request to a normal advertising device. You only need to enable central to accept extended advertisements and configure the central to scan on the Coded PHY. I can strongly recommend reading this article from novelbits which explains what Coded PHY is and how it works.

"For example, this procedure can be used to switch to using the Coded PHY after two devices have connected using the standard 1M PHY"

Now I know what to do.

1.52840 to 52840: connect with 1Mbit PHY and switch to the Coded PHY.

2.52832 to 52840: connect with 1Mbit PHY and always use 1Mbit PHY.
