Using NVMC with active Radio

[Wojciech Jasko]

Hi,

I would like to ask if it is possible to use both Radio and NVMC at the same time (no SoftDevice)?

My scenario:

• Start Radio and configure RX mode.
• Write/erase sth.
• Process received packet over the radio.
• Start Radio...
• Write/erase sth.
• ...

I know that during NVMC operations CPU does not execute code from Flash, but I assume that Radio is operational and EasyDMA access to RAM is working.

Could some confirm my assumptions?

Hi

Is there any particular reason that you don't want to use the SoftDevice? Your assumption is correct, as only the CPU is halted while NVMC is active. When using the radio, the SoftDevice is there to help you manage things like flash operations, etc. so that they don't interfere with the radio. We strongly recommend using the SoftDevice.

Best regards,

Simon

Hi

Thanks for the answer. I am doing it to optimize radio utilization (power consumption is not a concern) and what is more important to reduce the time when the CPU is blocked. For my application, it is not acceptable to block CPU for several ms.
