Description: A central connects to 16 peripherals, then disconnects and reconnects 3 times. The free heap memory is sampled for each connection event, and we wish to see that in each connection the heap allocation is constant. In loop 0 there is a difference of about ~400 Bytes in each connection, compared to loops 1 and 2. Also see a discrepancy in Multi-Role with 4 connections to peripherals as the central, and 4 connected to centrals as the peripheral.
