Ibeacon abvertisemt not working in changing of connectable mode

Hi Sowmiya,

Thank you for posting your question online.
You are not able to see your device advertising in connectable mode because of the advertising Data.
If you go on the user_config.h file:

/*
 ****************************************************************************************
 *
 * Advertising or scan response data for the following cases:
 *
 * - ADV_IND: Connectable undirected advertising event.
 *    - The maximum length of the user defined advertising data shall be 28 bytes.
 *    - The Flags data type are written by the related ROM function, hence the user shall
 *      not include them in the advertising data. The related ROM function adds 3 bytes in
 *      the start of the advertising data that are to be transmitted over the air.
 *    - The maximum length of the user defined response data shall be 31 bytes.
 *
 * - ADV_NONCONN_IND: Non-connectable undirected advertising event.
 *    - The maximum length of the user defined advertising data shall be 31 bytes.
 *    - The Flags data type may be omitted, hence the user can use all the 31 bytes for
 *      data.
 *    - The scan response data shall be empty.
 *
 * - ADV_SCAN_IND: Scannable undirected advertising event.
 *    - The maximum length of the user defined advertising data shall be 31 bytes.
 *    - The Flags data type may be omitted, hence the user can use all the 31 bytes for
 *      data.
 *    - The maximum length of the user defined response data shall be 31 bytes.

thanks , now i have tried to enable logs to check in uart by adding uart files and headers in  main ,but not even it showing any logs which i have modified after that when i am connecting the device its shows DAP ERROR while reading DP-CTrl register. how to recoer from this state . its urgent i am not even able to check with logs . 

i have tried the defualt blinky example i am able to see the logs in terminal  , but the changes i have done on iBEACON example is not even advertising in non connectable after adding the uart printf_string statement .

is there any sample application code to check  with logs on IBEACON Advertisementl. ?wanted to know wthether the application is running or not .

Awaiting for reply..

thanks,

Sowmiya

Hi Sowmiya,

Thank you for the reply.
I am not really sure what kind of configurations you have done on the ibeacon project.
First of all you should go on the da1458x_config_basic.h file and define CFG_PRINTF:

/****************************************************************************************************************/
/* UART Console Print. If CFG_PRINTF is defined, serial interface logging mechanism will be enabled.            */
/* If CFG_PRINTF_UART2 is defined, then serial interface logging mechanism is implemented using UART2, else UART1 */
/* will be used.                                                                                                */
/****************************************************************************************************************/
#define CFG_PRINTF
#ifdef CFG_PRINTF
    #define CFG_PRINTF_UART2
#endif

#include "arch_console.h"

		if(periph_counter ==0)
		{
			arch_printf("Booting Sequence \r\n");
		}
		else{
			arch_printf("Wake-up from Extended Sleep \r\n");
			arch_printf("counter: %02d \r\n", periph_counter);
		}
		periph_counter ++;

thanks for the quick reply , i am new to this controller.

i had did the same , please check the attached images.. 

and in sdk driver added uart files.

then my main file user_app.c  chnages has below..

for the connetable mode advterisement also changed in the same file.

in user_confg.h file

#define USER_ADVERTISE_DATA "\x03"\

is anything i had missed ? please check the files attached

Hi Sowmiya,

Thank you for the reply.
From what I can see you have not defined the CFG_PRINTF inside the da1458x_config_basic.h file.
You should also use the function:

arch_printf("Hello World");

	struct gapm_start_advertise_cmd *cmd = app_easy_gap_undirected_advertise_get_active();

yes , thanks for the response but now my device is in DAP ERROR state not even detecting to flash the firmware .

void user_app_on_init(void)
{
    /* If we have booted from flash then it will still be in active mode, power down to 
         reduce current consumption. */
    (void)spi_flash_power_down();	
    
    #if defined (__DA14531__) && defined (TX_POWER_2d5Bm)
            /* Set output power to maximum value (+2.5dBm) */
            rf_pa_pwr_set(RF_TX_PWR_LVL_PLUS_2d5);
    #endif

    default_app_on_init();
	
	 system_init();
	 printf_string(UART, "\n\r\n\r");
    printf_string(UART, "***************\n\r");
    printf_string(UART, "* BLINKY DEMO *\n\r");
    printf_string(UART, "***************\n\r");
	
}

did this changes before flashed this firmware now it is in error state .

how to recover the device from DAP error while reading  DAP -ctrl register state .?

thanks ,

sowmiya

Hi Sowmiya,

Thank you for the reply.
Why have you inserted the system_init function inside the user_app_on_init callback function?
This is the reason why your device has crashed.
The device has finished the booting sequence and the initialization of all the peripherals and then you call the system_init again unexpectedly. 
Please remove it, use the arch_printf function to print messages, and if you want to test undirected connectable advertising please check the available examples on the SDK.

Kind Regards,
OV_Renesas

yes , i will check with the examples but now how to recover from the crash state ? is there any way to come out error state then only i can able to do the further changes.

is it possible to overcome from the DAP error state ?

thanks ,

sowmiya

Can you share more detail what are you trying to implement?
Why have you configured the ibeacon example this way? You could just use the ble_app_peripheral example which is inside the SDK for undirected advertising, and you will not need to make so many configurations.

i wanted to do ibeacon advertisement with connectable mode . with out connectable mode i did the ibeacon advertisemt .

OV_Renesas said:

The Advertising Data can transmit 31 bytes of information. But the first 3 bytes are used for Flags (as stated in the Bluetooth Specification) in the undirected connectable advertising. In the non-connectable advertising mode, we are able to use all the 31bytes for our own information. 
This is happening on the ibeacon example you are working on. 
We have stated that we are working with non-connectable advertising, and we are saving information on all 31 bytes of the Advertising Data.

is it possible to get all 31 bytes with connectable mode ?  i have tried in ble_app_peripheral with connectable mode able write data with exiiting service also can we chnage the defualt service to custom service ? is it possible to change the advertisemt of ibeacon format with the manufacture data ?how many bytes can advertise ?

Thanks ,

Sowmiya

Hi Sowmiya,

Thank you for the reply.
Ibeacons are by default advertising in non-connectable mode. Since you want to use Ibeacon with connectable mode you should enter the ibeacon data into the advertising data and keep in mind to occupy 29 bytes at max. 
Unfortunately, it is not possible to get all 31 bytes with connectable mode. The first 3 bytes used for Flags are necessary and specified in the Bluetooth SIG Specification.
Can you clarify what you mean by the following:

The ibeacon format is a fixed format which you can not modify. You could create your own custom advertising format and insert the Manufacturer data there.
Please check also our Eddystone Beacon example available on our GitRepo: BLE_SDK6_examples/interfaces/wakeup_hibernation_ext_timer at main · dialog-semiconductor/BLE_SDK6_examples · GitHub
The Eddystone Beacon supports an open format, so you could insert custom data (for instance, manufacturer data). In this example you can see how they have configured ADC values and the Battery Service values showing up on the advertising data.
