Missing characteristics declaration value.

[Swapnil]

I am calling certain services and I can see this output on my UART listener:

0.000013 : UART Start!

0.385355 : BLE Stack Initialized

0.385581 : Peer Manager Initialized

0.385765 : MAC Address xx:xx:xx:xx:xx:xx

0.386151 : Battery Service Initialized

0.386315 : Sensorsim Initialized

0.386581 : Handle list for temperature service 0x11: 0013 0014

0.386824 : Temperature Service Initialized

0.387246 : Handle list for sensor service 0x15: 0017 0018 001a 001b 001d 001e 0020 0021 0023 0024

0.387736 : Sensor Service Initialized

0.388074 : Handle list for manager service 0x25: 0027 0000 0029 002a

In this case 0x12, 0x16 and 0x26 isn't included in the char_handles-struct from the corresponding services.

I am not getting why these values are missing.

These handle numbers are most likely used somewhere else. Why do you want these numbers to be consecutive? They are stored in the handle holder, so that you could use the variable instead of the number.

[Swapnil]

Well they are apperently already consecutive once the services and characteristics are initialized properly and I just wanted to have some option to read-back all handle-values after the initialization is done as an error-check.

Is there a way to access that handle-holder that you mentioned?

When you call sd_ble_gatts_characteristic_add(), the last parameter is where the handles for this characteristics is stored. If you want to check the content of a handle, you can call sd_ble_gatts_value_get() with the handle as parameter. For instance in the ble_app_uart example, the handles of the nus service is stored in the struct ble_nus_t m_nus, and you can access the handles with m_nus.tx_handles.value_handle, m_nus.rx_handles.value_handle, etc.
