Changing advertising data STM32WPAN

Hello,

 

I have custom PCB with STM32WB5MM module configured as beacon. I am successfully advertising configured data.

I have configured a task in sequencer (the task gets executed, checked with debugging). When I leave task empty, the BLE advertises, but when I add function to update adv data, the advertising stops.

Configured data manufacturer specific data: 100000000000000090 

"New" configured data manufacturer specific data: 100000000011111190 

 

My function:

 

 

void MyTask(void){

	uint8_t alt_AdvData[28] =
	{
	 2, AD_TYPE_TX_POWER_LEVEL, 0 /* -0.15dBm */, /* Transmission Power */
	 7, AD_TYPE_COMPLETE_LOCAL_NAME, 'F', 'P', '0', '0', '0', '1', /* Complete name */
	 3, AD_TYPE_16_BIT_SERV_UUID_CMPLT_LIST, 0x0D, 0x18,
	 12, AD_TYPE_MANUFACTURER_SPECIFIC_DATA, 0x30, 0x00, 0x10 /* */, 0x00 /* */, 0x00 /* */, 0x00 /* */, 0x00 /* */, 0x11 /* */, 0x11 /* */, 0x11 /* */, 0x90 /* */,
	};
	aci_gap_update_adv_data(sizeof(alt_AdvData), (uint8_t*) alt_AdvData);
}

 

 

In "alt_AdvData" I currently store "new data" to advertise, at later point they will be dynamically changed.
