Detailed Description

Function Documentation

ble_gatt_mtu_get()

uint16_t ble_gatt_mtu_get	(	uint8_t	conn_idx,
		uint16_t *	p_mtu
	)

Get the current ATT_MTU size for a given connection.

Parameters

[in]	conn_idx	Current connection index.
[out]	p_mtu	ATT_MTU size for the given connection.

Return values

SDK_SUCCESS	Successfully get ATT_MTU.
SDK_ERR_INVALID_PARAM	Invalid parameter(s) supplied.

ble_gatt_mtu_set()

uint16_t ble_gatt_mtu_set

(

uint16_t

mtu

)

Set ATT_MTU size.

Parameters

[in]

mtu

ATT_MTU size.

Note

This function should be called before exchange MTU operation. This MTU size is used to all connections. If not set these parameters, the stack will config the default value as (max_mtu = 512).

Return values

SDK_SUCCESS	Successfully get ATT_MTU.
SDK_ERR_DISALLOWED	Operation is disallowed.
