I was thinking about Lesson 2 (on advertising) to refresh you on the different types. From the last sentence in your ticket the course tip seemed appropriate:

[quote user=""]I did not enable directed advertising; not sure what this is or if I want it but I remember having an issue turning it on.[/quote]

I will adress the contents of your ticket in more detail this week.

[quote user=""]I am having great success on first pair/bond. Subsequent connections do not do as well. I have done full recovery.[/quote]

My initial hypothesis is that the bonding procedure causes the PC to store the bonding information which causes issues if the nRF5340 tries to initiate a new bonding when the PC recognizes the device as already bonded. Are you able to successfully bond a second time if you "forget" the device before restarting the bonding procedure?

No, I don't see a fundamentals course covering this topic. I don't see anything better than lesson 3/5 and that's not going to over this error.

This feels like a punt. Yes, the computer is turned on. If there's something relevant there, please specify.

Hello,

You will find some useful information about this in the Bluetooth Low Energy fundamentals course on DevAcademy.

Let us know if the course is not sufficient for you to progress with this issue.

Best regards,
