Detailed Description
Module for storing data on BLE connections.
This module stores certain states for each connection, which can be queried by connection handle. The module uses BLE events to keep the states updated.
In addition to the preprogrammed states, this module can also keep track of a number of binary user states, or user flags. These are reset to 0 for new connections, but otherwise not touched by this module.
This module uses the Mapped flags module, with connection handles as keys and the connection states as flags.
- Note:
- A connection handle is not immediately invalidated when it is disconnected. Certain states, such as the role, can still be queried until the next time a new connection is established to any device.
To function properly, this module must be provided with BLE events from the SoftDevice through the ble_conn_state_on_ble_evt() function. This module should be the first to receive BLE events if they are dispatched to multiple modules.
