Hello Alberto,
There are 2 timings to consider on protocol switching:
- Hardware level switching: Modem switch time at hardware level.
- Application level switching on top of stacks: Takes into account modem switch time and software overhead including RTOS context switching.
The modem switch time average from BLE to 802.15.4 (and viceversa) is ~40µs.
For the application level switching, this will vary from stack to stack. We will run some tests and get back to you.
