Where to use lib_aci_set_local_data

[DennisEB]

Hello Nordic Team, i've get my things working and i figured out how i can set service data and to display it in nRF Master Control.

Now i want to CHANGE my service data every 5 seconds for example.

Till now, i've used lib_aci_set_local_data like it is set in BLE-Broadcast example (maybe you open this sketch and see) within part: case ACI_DEVICE_STANDBY:

I tried to use it outside the switch-case, but then i get "You're in a while(1) loop" with ACI D message.

As long as i set it within case ACI_DEVICE_STANDBY: it is working for the first set of data, but then never changes.

How and where do i have to set local data without getting this while(1) error?

Noone here to help?

What is the command response you are getting? Since you are planning on updating your service data every 5 seconds, have you considered using notifications?

[DennisEB]

The command response is ACI COMMAND D, Evt Cmd respone: error. Arduino is in a while(1) loop . No i can't use notifications because will and have to use advertising service data.

Any chance you could share your project? I looked at the broadcast and as far as I can see we are not using set_local_data there, but I could be wrong. This should be fairly straight forward as long as the set pipe property is set (would be #define PIPE_GAP_DEVICE_NAME_SET in services.h with the _SET postfix). Note that if you don't want to share your project here you could create a support case instead.

Hi Runar, in services.h it looks like this:

 /* Service: Gap - Characteristic: Device name - Pipe: SET */
#define PIPE_GAP_DEVICE_NAME_SET          1
#define PIPE_GAP_DEVICE_NAME_SET_MAX_SIZE 2

/* Service: GPS_info - Characteristic: GPSsend - Pipe: BROADCAST */
#define PIPE_GPS_INFO_GPSSEND_BROADCAST          2
#define PIPE_GPS_INFO_GPSSEND_BROADCAST_MAX_SIZE 16

And in my sketch, within the case-part i use:

case ACI_DEVICE_STANDBY:
            
            // Open advertising pipe on pipe 2
            
            lib_aci_open_adv_pipe(2);
            // Start broadcasting
            lib_aci_broadcast(0x1000, 0x1000);
            lib_aci_set_local_data(&aci_state, 2,(uint8_t *) &Nummer1, sizeof(Nummer1)); // 
            break;

Cut setlocaldata in this part and cory it outside all case-statements will cause ACI D Err

Can you print out the Status code given in the Command response event? Chapter 28.1 ACI Status Code in Product specification.

I assume you might also be getting a PipeErrorEvent?
