LAUNCHXL-CC1352R1: How to add GAP Scanning to Project Zero?

Matthias Ringwald

Hi. I'm trying to add GAP Scanning to Project Zero. For this, I've updated TOOLS/build_config.opt of the stack library project from

-DHOST_CONFIG=PERIPHERAL_CFG

-DHOST_CONFIG=PERIPHERAL_CFG+OBSERVER_CFG

And changed Application/ProjectZero.c in the main project from

GAP_DeviceInit(GAP_PROFILE_PERIPHERAL, selfEntity, ADDRMODE_PUBLIC, NULL);

GAP_DeviceInit( /* GAP_PROFILE_PERIPHERAL | GAP_PROFILE_OBSERVER, selfEntity, ADDRMODE_PUBLIC, NULL);

However, GAP_DeviceInit returns status = 0x02 now. What does error 0x02 mean? Where are the error codes defined?

How can I add GAP Scanning?

(I've tried the multi-role example, but the code gets stuck in NOROM_SetupTrimDevice() at chipinfo.c:204 - which might be related to using an early device, I'll re-try with new Launchpad soon. I'm also irritated that Project Zero has about 200 kB code, while multi-role only has 100 kB).

Thanks

Matthias

Hi Matthias,

Assigning this to a team member for follow-up

Hi Matthias,

Error code 0x02 means invalid parameter. Here is the API documentation for GAP_DeviceInit.

That should work but maybe it's the comment in GAP_DeviceInit that causes problems?

Thanks,
Elin

Hi Elin

Thanks for looking up the error code. The opening comment was a copy & paste error.

I just tried to configure Peripheral + Central as in the multi-role example, and that worked.

Trying Peripheral + Observer again I still get 0x02. How can I find out which parameter is invalid?

Is Peripheral + Observer a supported configuration? The build_config.opt did suggest so.

Anyway, I can continue using the Peripheral + Central configuration.

Hi Matthias,

Apologies for the delay. Have you managed to make it work?

Peripheral + Observer is a supported configuration so it should not give an error.

Thanks,
Elin

Hi Elin

I just tried multi-role example with current CC2552R1 Launchpad and the init works there. That's good enough.

So, the problem before was either caused by older silicon of the CC1352R1 or the Project Zero example (with stack + app projects).

I'm fine here. Thanks.
