Detailed Description

BLE L2CAP connection configuration parameters, set with sd_ble_cfg_set.

Note: These parameters are set per connection, so all L2CAP channels created on this connection will have the same parameters.

Return values

NRF_ERROR_INVALID_PARAM	One or more of the following is true: rx_mps is smaller than BLE_L2CAP_MPS_MIN. tx_mps is smaller than BLE_L2CAP_MPS_MIN. ch_count is greater than BLE_L2CAP_CH_COUNT_MAX.
NRF_ERROR_NO_MEM	rx_mps or tx_mps is set too high.

Field Documentation

uint8_t ble_l2cap_conn_cfg_t::ch_count

      Number of L2CAP channels the application can create per connection

with this configuration. The default value is zero, the maximum value is BLE_L2CAP_CH_COUNT_MAX.

Note: if this parameter is set to zero, all other parameters in ble_l2cap_conn_cfg_t are ignored.

uint16_t ble_l2cap_conn_cfg_t::rx_mps

        The maximum L2CAP PDU payload size, in bytes, that L2CAP shall

be able to receive on L2CAP channels on connections with this configuration. The minimum value is BLE_L2CAP_MPS_MIN.

uint8_t ble_l2cap_conn_cfg_t::rx_queue_size

 Number of SDU data buffers that can be queued for reception per

L2CAP channel. The minimum value is one.

uint16_t ble_l2cap_conn_cfg_t::tx_mps

        The maximum L2CAP PDU payload size, in bytes, that L2CAP shall

be able to transmit on L2CAP channels on connections with this configuration. The minimum value is BLE_L2CAP_MPS_MIN.

uint8_t ble_l2cap_conn_cfg_t::tx_queue_size

 Number of SDU data buffers that can be queued for transmission

per L2CAP channel. The minimum value is one.
