I ported the SPP to other routines.However, the RFCOMM registration fails
call wiced_bt_rfcomm_create_connection()
rfcomm_result = 6/8
check wiced_bt_rfcomm_result_t
6 = WICED_BT_RFCOMM_NO_RESOURCES, /**< No Resources */
8 = WICED_BT_RFCOMM_INVALID_MTU, /**< Invalid MTU */
I've seen it many times
But add the other code you need in the routine that contains the SPP.
There will be no such error

Hi
Not sure if this issue fixed for you. Could you please try the below suggestions:
1: Could you please increase the buffer pool sizes in the wiced_bt_cfg.c file . Example:
const wiced_bt_cfg_buf_pool_t wiced_bt_cfg_buf_pools[WICED_BT_CFG_NUM_BUF_POOLS] =
{
/* { buf_size, buf_count, }, */
{ 64, 16, }, /* Small Buffer Pool */
{ 272, 8, }, /* Medium Buffer Pool (used for HCI & RFCOMM control messages, min recommended size is 360) */
{ 1056, 3, }, /* Large Buffer Pool (used for HCI ACL messages) */
{ 1056, 2, }, /* Extra Large Buffer Pool (used for SDP Discovery) */
};
2: As of now, I can see the MTU size in the config file of your project is set to 365. Could you please set max_mtu_size to 515 . Please try the above modifications first.
3: If still not working, can you please change the buffer size passing to API wiced_bt_rfcomm_init and let us know the API result.
4: Not sure how did you tested the project. Please let me know
5: If your requirement is just to merge A2dp sink + SPP profile. Can you try it with the APIs in spp.c ,(removing the hci_control_spp ) and please let us know the API results if not working.
