No, sorry. It’s been a while since I’ve implemented this and cannot remember any example projects for this. Feel free to reach out to my public email with any questions.

Hi Jon!

Thanks for responding to my question! I have reviewed the direct advertising and whitelisting feature and it seems like that's what we might need for this requirement! I was wondering if you would be able to provide a link to a specific example for this implementation.

Thanks!

Hi Mohammed,

As mentioned by Jon, the way to prevent connecting to random devices is to use whitelisting feature or directed advertising.

I also work for a medical device company, so have the same requirement. This can actually be easily achieved by using white lists. Our device has two states for advertising, direct advertising (only advertising to devices on the whitelist) and normal advertising where any device can bond and be added to the white list. We leave the default state on power up as direct advertising and require users to manually enter normal advertising mode to enable devices to be added to the white list. Look into examples around direct advertising.
