BLE connection parameter and Wiced_bt_gatt_send_read

Unsolved

Hi.

I have two question about Bluetooth connection.

One in about connection parameter (WICED_BT_CFG_CONN_MIN_INTERVAL, WICED_BT_CFG_CONN_MAX_INTERVAL, WICED_BT_CFG_CONN_SUPERVISION_TIMEOUT).

Is it possible to have a WICED_BT_CFG_DEFAULT_CONN_SUPERVISION_TIMEOUT longer then 32 seconds? I need to have 60 or 90 seconds.

Second one is. I'm conneted with a device and I send it a read_request (wiced_bt_gatt_send_read). I notice that i can't do an other request until the device has answer to my first one. System return me BUSY Error (WICED_BT_GATT_BUSY) if I'll do it (return = wiced_bt_gatt_send_read (connection_handle, GATT_READ_BY_HANDLE, &parameter )

Salvatore - Take a look at this discussion on WICED support forum for more info regarding BLE connection parameters (including WICED_BT_CFG_DEFAULT_CONN_SUPERVISION_TIMEOUT) https://community.cypress.com/message/28133#28133
