nrf connect SDK coded PHY nrf52833/20

Muhammad Usman

Hi All! 

I am using nrf52833/20DK. I have a few general questions regarding the nrf connect SDK.

1)nrf connect sdk supports connectable coded PHY advertisement? if yes can you please mention the example with the SDK version?

2)Is there any example in nrf52 SDK OR nrf connect SDK that supports coded PHY beacons with ACK to sender? This means if a packet/beacon is sent to the receiver then it will send back the ACK to the sender to ensure at the sender's end that the message is received.

3)How many coded PHY concurrent connections can support nrf connect sdk & nrf52 SDK?Nimble mentioned that it supports 32 concurrent connections as mentioned in the link

Thanks in Advance!

    Hi,

    1) See the Bluetooth: Peripheral Heart Rate Monitor with Coded PHY example. It advertises and connects using Coded PHY.

    2) Advertisements do not produce ACKs back to the sender. This is by Bluetooth specification. There are two ways a scanner can send packets back to an advertiser:

    • One is if doing active scanning, where scannable advertisements will trigger a scan request from the scanner. However I am not aware of any hooks onto this where you can know on the advertiser side which scanner has sent a scan request.
    • The other is if doing connectable advertising, where the scanner (acting as initiator) may send a connection request.

    3) nRF5 SDK (using the SoftDevice) and nRF Connect SDK using the SoftDevice Controller has a maximum of 20 concurrent links.

    Please note that we are entering Easter vacation in Norway. You may have to wait until next week for answers to any follow-up questions.

    Regards,
