KW41Z BLE and 802.15.4 context switch time

[j_albertoibarra]

Hi All!

I am using BLE and 802.15.4 with KW41Z , and I want to know how much time takes to switch from BLE to 802.15.4 and vice versa. Any one knows this time?

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.
