How to read RSSI value on nrf_application or putty terminal

[sachin.singh]

Hi,

I need to print the RSSI value to the nrf app or putty terminal to check the RSSI value.

I have gone the structures "ble_gap" file to get the RSSI value and calling it in the main function.

After calling it into the main and checking it into the putty terminal it show the fixed value it never changes.

So I need guidance for the same to develop my code ...

Thanks

I'm not quite clear where you're trying to do this - in a mobile app, or in an nRF51 chip?

And which "RSSI" are you trying to display

• The Central's own signal strength,  at the central?
• The Peripheral's own signal strength, at the Peripheral?
• The Peripheral's signal strength, reported to the Central?
• other?

I need to display the RSSI value to Putty terminal screen after entering the command.

RSSI value should required between the

• The Peripheral's signal strength, reported to the Central

I am developing the same into "ble_app_uart" example and trying to send/printing the RSSI to the mobile app.

Looking for your help for the same.

Best Regards

So what have you tried so far?

Where are you stuck?

Have you studied the SDK documentation - in particular, the SoftDevice documentation - to find something which gives access to the RSSI ?

Hi Awneil,

I have studied on the "sd" API's to the RSSI to get it. 

They explained that we should have to start RSSI API before ADV starts and then get the RSSI value from the structures.

Even from the online examples I have tried to call those structures to get the RSSI value and then transmit it to the NUS to mobile app.

If you have some sample then please share it ... I need it urgently ...

Looking for your solution ....

Thanks

So show what you tried.

Tell what results you were expecting.

Tell what results you actually got.

Tell what debugging you have done to find any problems.

How to post source code:

Hi Awneil, 

I have followed this link for getting the RSSI value.

I have followed the structure as they have used for getting the RSSI value

"p_ble_evt->evt.gap_evt.params.scan_req_report.rssi not p_ble_evt->evt.gap_evt.params.adv_report.rssi"

I have placed above statement in my main just after "init" functions.

then in for(;;) body I have written this "rssi = p_ble_evt->evt.gap_evt.params.adv_report.rssi;" and get it via NUS services on mobile app. But it shows zero value.

I am not getting it is so, If I am going wrong then please guide me and correct for the wrong ...

Thanks

Hi Schin

I am happy to take a look at your main.c file if you can attach it in a reply. 

Then it is much easier to see what might be wrong in your code. 

Best regards
