continuously monitor rssi values of multiple specific ble devices

[standard8]

Hi everyone,
The title (hopefully) says it all. Unfortunately I could not find an example online, only a few using mqtt servers which I can't use in the scope of my project. I can successfully continuously monitor a single ble device or non-continuously, meaning not a stable connection, scanning for multiple ble devices and reading their rssi values. What I want is to get the current rssi values of 3 ble devices with known MAC addresses every 1 to 3 seconds. I am aware that there is a ble multi connect example and ble mesh examples in the official github repo, but I am not sure how to proceed or understand if this could be a solution for my needs. Has anybody managed to get something working in this regard?

scanning for multiple ble devices and reading their rssi values.

How does this not solve your problem?

because the connection is not stable. sometimes the esp only finds one device and i dont get a rssi reading for several minutes. I need to get a reading of all 3 devices every few seconds.

Are the devices constantly advertising ("general discoverability") or intermittently ("limited discoverability")?
