direct assignment to ble_gap_conn_params_t variable

[Joseph]

Hello Nordic support team,

Forgive me if I am asking a stupid question.

In the source file ble_conn_params.c, there is a function called ble_conn_params_init() and I found this direct assignment:

    m_preferred_conn_params = *p_init->p_conn_params;

but m_preferred_conn_params is a variable of ble_gap_conn_params_t which is a structure:

typedef struct {

uint16_t min_conn_interval;
/**< Minimum Connection Interval in 1.25 ms units, see @ref BLE_GAP_CP_LIMITS.*/

uint16_t max_conn_interval;
/**< Maximum Connection Interval in 1.25 ms units, see @ref BLE_GAP_CP_LIMITS.*/

uint16_t slave_latency;
/**< Slave Latency in number of connection events, see @ref BLE_GAP_CP_LIMITS.*/

uint16_t conn_sup_timeout;
/**< Connection Supervision Timeout in 10 ms units, see @ref BLE_GAP_CP_LIMITS.*/

} ble_gap_conn_params_t;

So why this direct assignment is possible?

Best Regards, Joseph

Direct assignment of a variable like is valid in C since it copies all struct fields at once, simplifying code and reducing errors from manual copying. Understanding these embedded C basics is crucial for efficient BLE development.

crazy finding this old thread from 12 years ago when i was just searching for unblocked games and nordic support answers today. that ble conn params init function has been part of the sdk forever and it works fine. joseph was probably just confused by how the compiler handles structure copying without needing a memcpy call.
