The parameter of LE credit based connection request packet sending. More...

`#include <ble_l2cap.h>`

## Data Fields
uint16_t | le_psm
uint16_t | local_cid
uint16_t | local_credits
uint16_t | mtu
uint16_t | mps

## Detailed Description

The parameter of LE credit based connection request packet sending.

Note
  The le_psm should be registered by the peer device, otherwise the peer device will reject this request with result of LE_PSM not supported.
  The local_cid should be 0x0040-0x007F. If the local_cid is set to 0, the stack will assign it dynamically.
  The local_credit is required to be sure that at least one SDU can be received, otherwise the stack will use the default value: (MTU + MPS + 1) /MPS + 1.
  The MTU range is [23~max_mtu].
  The MPS range is [23~max_mps].
  About max_mtu and max_mps config, please see ble_gap_l2cap_params_set.

## Field Documentation

## ◆ le_psm

uint16_t lecb_conn_req_t::le_psm

The le_psm number.

## ◆ local_cid

uint16_t lecb_conn_req_t::local_cid

The local CID.

## ◆ local_credits

uint16_t lecb_conn_req_t::local_credits

The local credits indicate the number of LE-frames that the peer device can send to the L2CAP layer entity sending the LE Credit Based Connection Request.

## ◆ mps

uint16_t lecb_conn_req_t::mps

The MPS field specifies the maximum payload size (in octets) that the L2CAP layer entity sending the LE Credit Based Connection Request is capable of receiving on this channel.

## ◆ mtu

uint16_t lecb_conn_req_t::mtu

The MTU field specifies the maximum SDU size (in octets) that the L2CAP layer entity sending the LE Credit Based Connection Request can receive on this channel.
