46 * @brief Tx Power Service Client module.
47 *
48 * @details The Tx Power Service Client contains the APIs and types, which can be used by the
49 * application to discovery of Tx Power Service of peer and interact with it.
50 *
51 * The application must provide an event handler to register, then call \ref tps_client_init().
52 * After Tx Power Service Client discoveries peer Tx Power Service, application can call
53 * \ref tps_c_tx_power_level_read() to get tx power data from peer.
