Hi,
Thank you all for your reply, I’m not sure if using attributes this is the best approach for this problem, so far is the only I have found.
Just to add some context the idea is stream compressed audio data from a device to the other using BLE 5.1 in prototyping stage and then migrate to BLE 5.2 isochronous channels.
For now I’ll try packet fragmentation and see what speeds are archived.
