How does google "chrome://bluetooth-internals" bluetooth tool show Read Encrypted and Write Encrypted

[zero]

Dear support team,
We need to show support for Read Encrypted and Write Encrypted on the "chrome://bluetooth-internals" Bluetooth tool, as shown below:

I modified it based on the \examples\ble_peripheral\ble_app_gls example, but it was not successful. How to modify it?

Hi Zero

I'm not familiar at all with Chrome's Bluetooth internals tool, so I'm not 100% sure what toggles these read and write encrypted boxes, but I'd assume it's something like the encrypted mode for characteristic read/write permissions that must be toggled. Please check out this ticket for how to set up characteristics in secure mode. I think you also need to add secure bonding like what is done in the ble_app_gls example for instance to make sure you have an encrypted connection and the devices are bonded.

Best regards,

Security Mode 1 Level 4,this is the highest level of encryption,but in the web tool, it still doesn`t work.I have tried all the encryption modes supported by characteristic.

I'll ask the Windows developers internally if they know what is necessary to check these boxes, but I can't guarantee that they know, so I'd recommend reaching out to Google/Chrome support to ask what security mode/level is required to do so.

I also see that you only link to the encryption mode of the connection though. Have you also checked out the characteristic security modes with read/write permissions, like &cccd_md.read_perm and cccd_md.write_perm?

Best regards,
