what exactly ble_beacon stack is used for? what it does and can it be used to advertise or send  user data (like string) and receive notifications from other devices ...can anybody explain which one is the advertising packet in beacon stack..how advertising packet is made and hoe it is transmitted....thank you

Hi,

What exactly do you refer to by ble_beacon stack? We provide a Bluetooth Protocol stack (the softdevice), and Beacon/Eddystone examples in the SDK.

Best regards,

in ble_beacon stack(i am using nrf52832 SDK 15) 

#define APP_BEACON_INFO_LENGTH           0x17 /**< Total length of information advertised by the Beacon. */
#define APP_ADV_DATA_LENGTH                  0x15 /**< Length of manufacturer specific data in the advertisement. */

can we change APP_BEACON_INFO_LENGTH and APP_ADV_DATA_LENGTH....so that more than 21 byte data can be sent... i tried changing 

static uint8_t              m_enc_advdata[BLE_GAP_ADV_SET_DATA_SIZE_MAX] to

static uint8_t              m_enc_advdata[BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_MAX_SUPPORTED]

but it didnt help...if we cant change data length then why...please explain

how to update or send new UUID ...i want one UUID to be seen on nrf connect (mobile app) and on key prrressed second UUID to be seen on app....is it possible and how

[Jørgen Holmefjord]

Yes, it is possible, but the application does not implement such features by default. You will have to update the advertising data, for instance by calling advertising_init(), with the new UUID.

There is also no button handling in the example, so you will have to add this yourself. You can use BSP or the app_button library.
