Tool/software: Code Composer Studio
For long-distance needs, we use 1.50.00.71 the makes the following modifications.
Central device:
1. When requested to connection, the default use 500K PHY
2. After successful connection, we use the 1M + 2M + coded PHY
Peripheral:
1. Settings default PHY = 500K
2. after successful connection, set again PHY = 500K Request
Results:
After we power off and power on the central device several times(no more 15 times), the Peripheral crash and cannot connect again . However, if Central and Peripheral is used only 1M PHY, there is no this issue.
