Sorry, that's my neglect.

Hardware: nrf52832 board

SDK: 16.0.0

Softdevice has been loaded.

And nothing happened.

Did you also load the SoftDevice?

Do you get anything at all on your terminal?

Maybe post a a screenshot ?

You didn't say what hardware you're using ...

Yes, I have loaded it.

But nothing happened when I use Root Commands directly like 'advertise on' by uart.

In fact, I am confused with the method that how to usage these commands.

Can u give me some detail procedures?

and have you actually loaded & run the example?

Like I said:

Hi awneil,

I have read this doc, and how can i use these commands? Write one command by uart?

Any other usage example doc/url?

Just advertising packets?

So you're basically building a scanner.

That's a fundamental part of any central device - so you could pick that out of any of the Central examples.

You could start with this:

Okay，thanks a lot.

And the question has changed now.

How to use softdevice to get packets at any channel, not just channel 37, 38, 39？

awneil — Fri, 17 Jul 2020 09:51:35 GMT

So use the SoftDevice!

That what a reason that i want to get further help to fulfill it.

My boss compels me to finish it.:(

It will take a whole lot more effort to "just" (sic) do that manually from scratch than to just use the SoftDevice!

With the SoftDevice, it is trivial.

Yoole — Fri, 17 Jul 2020 09:34:38 GMT

Hmmm, maybe a little.

But, I just wanna to get information from ble_advertising packets at any channel, not the whole complex protocol.

Do you have any experience with working at such a low level with complex protocols like BLE ?

The whole reason Nordic provide the SoftDevice is because this is not an easy thing to do!
