Problem description:

• When trying to connect to more than 2 Simple central devices with All 1M PHYs 1 Simple peripheral the connections are not stable. (Unexpected Connections Terminated after less than 150 minutes)

Problem reproducibility:

• 100% - after establishing more than 2 connections (between the SP and each of the SC devices) the connection terminates before the expected time
• Expected: 12H
• Actual: 150min to 6H

Steps to reproduce the issue:

• Establish 2 or more connections between simple central devices with all 1M and one simple peripheral
• Try to hold connection for 12 hours

Note:

This bug might affect the Simple Peripheral role part in the Multi-role app as well, since we encountered the same problem with Multi role app as DUT trying to hold connection with 4 Simple centrals and 4 Simple peripherals.

Same test pass 24H with 2 connections
