RE: define queue in a structure

Hi,

I might be misunderstanding you scenario here, but most of these GATT based queues are handled with the nrf_ble_gq library, which is used by most examples in nRF5 SDK v17. Please correct me if I have not understood your scenario fully.

Here's a high-level documentation that explains the BLE GATT queue: https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/lib_ble_gatt_queue.html

But not understand the Log code, actually don't get the whole LOG module structure.

Have you tried enabling logging (and set sdk_config.h::NRF_QUEUE_CONFIG_LOG_ENABLED to '1') to see how it behaves for the specific module?

Have you checked the documentation chapter on the subject?

https://docs.nordicsemi.com/bundle/sdk_nrf5_v17.1.0/page/lib_nrf_log.html

[quote user="OldXiao"]Except log function, it looks like we can just define a nrf_queue_t instance,allocate memory,and then we can process with queue functions.[/quote]

Have you looked at how this is implemented in other central implemented services, like ble_nus_c for instance? Follow the p_gatt_queue and other vars/API calls to the nrf_ble_gq module.

Kind regards,

Håkon

I misunderstanded the nrf_queue_cb_t type,I thought it is a callback function.It is not.

But not understand the Log code, actually don't get the whole LOG module structure.

Except log function, it looks like we can just define a nrf_queue_t instance,allocate memory,and then we can process with queue functions.
