[nRF54L15]2.4g frequency switching time

[zero]

Dear devzone,
nRF54L15 runs private 2.4g, and needs to switch from 2400MHz to 2500MHz. How long is this period? How long is it to switch from 2400MHz to 2410MHz? I see from the specification that the time from RXEN task to READY event in fast mode is 40μs, but the actual time may be slightly longer. Is there any data in this regard?

Hi Zero, 
I will check internally to see if I can get more information for you. Have you done any test on the switching time ? 
My understanding is that the switching between between 2400MHz to 2500MHz would take the same time as switching from 2400MHz to 2410MHz as the radio has to stop before switching. But I will keep you updated if I hear something else from the R&D team.

Hi Hung Bui，

Thank you for your support. Please let me know if you have any news.

Hi Zero,

I think you will have to write your own firmware to do the task. 
My suggestion is to take a look at the radio_test sample. The sample take the command to switch between channels from UART. But you can modify it to do the switching automatically. You then can use the time between when you set TASK_RXEN to the time you get the event EVENT_RXREADY
