Sniffer not functioning.

Hi
The first thing I spot with the debugger is that the code quickly gets stuck in the radio interrupt, which seems to get called over and over.

I see that you set various events to generate interrupts in the NRF_RADIO->INTENSET register. In this case you should also have several code snippets in the interrupt to handle the various events. As it is now I can't see that you process other events than the END event.

What you need is something like this...

if(NRF_RADIO->EVENTS_READY != 0)
{
  NRF_RADIO->EVENTS_READY = 0; 
  // Process the READY event
}
if(NRF_RADIO->EVENTS_END != 0)
{
  NRF_RADIO->EVENTS_END = 0;
  // Process the END event
}
// And similar for the ADDRESS and PAYLOAD events

Best regards

Sorry, I explained a bit poorly. I mean that if you zip your entire example folder then I can just move it into my SDK and make it work. You don't have to move anything.

I expect that you have a folder that looks something like this: \nRF5_SDK_12.2.0\examples\peripheral\my_example\

In this case you should just zip the entire 'my_example' folder (or whatever you have called it), and send that to me. Then I can unzip it into my own SDK examples folder and all the references should work.

Best regards

I will check this out. I am using SDK v12.2 SES. Also I am using PCA 10028 and not PCA 10040. Can u please clarify the last thing you mentioned above. U mean I move this entire zipped folder into the ppi example folder which is my project?

Thanks!!!

Sorry to be a pain, but I still can't get it to compile :(

I meant the top example folder, including the main.c file, the sdk_config.h file and all the project files. I tried to piece together your project myself, but as I fix one error a new one pops up (probably because I have the wrong config file, or the wrong SDK version).

As an example, see the following project:
ble_app_hrs.zip

Then you just have to copy that folder into one of the SDK example folder and the project will compile.

Also, can you let me know which version of the SDK you are using?

Best regards

Hi
What I mean is if you can zip your project folder, with all the source and project files in it. Then all the references in the project should work, so that it can find all the files.

Best regards

Sure. You can find the project attached at the top.

Thanks!!!

Hi Khosla

Could you zip and attach the entire project?

Then I might be able to run it, and try to figure out what is happening.

Best regards

Hi I have seen this code. But i coudn't find anything as such. If APP_ERROR_CHECK fails I won't have noticed it unless i am in debug mode. So i tried running in debug mode to see if all is ok. two ways i did it:

Setting a breakpoint in the while loop and verify that it stops there
in debug mode, after executing for a little while, pause execution and see where it is.

On doing the second way mentioned above, it started in a paused state and then when i run it, i get a hardfault with no call stack. Whether this indicates too small main or may be stack size?

However, when i set a breakpoint in while loop in the main, i got the hard fault before the breakpoint. But when i set some point very early in the main, it was okay then. But again i set it some time later but before the while only and agian it was a hard fault.

Can you please comment on what's going wrong over here.

And if its some problem with the stack size, how do i rectify it.

You can refer to my updated main.c file attached at the top.

Thanks!!!

Could you please have a look at the code for the solar beacon: https://github.com/NordicSemiconductor/solar_sensor_beacon/blob/master/src/hal_radio.c

It is also an implementation of BLE advertising using RADIO registers only.
