Hi,
I've another thread with the same question but that thread is locked so I cannot reply at that thread. So I re-created it here.
I'm using CYW43012, which is controlled by another MCU through UART flow-control with standard HCI protocol (not Wiced).
Currently, I'm able to make it advertise normally. However, when I'm using a phone to connect to it, it always fails.
When I look into the HCI data, here is the result when phone is trying to connect to Cypress:
---------------------------------
BLE_GAP_EVT_ADV_START --------------------------> Start advertising normally
hciEvtProcessMsg: evt=3E, data=0A00400001010FBA4B90174200000000000000000000000018000000480001
DM_CONN_OPEN_IND, r=0, cid=1 -------------------> Phone is trying to connect
hciEvtProcessMsg: evt=3E, data=14400000 --------> Channel selection Algorithm event
hciEvtProcessMsg: evt=FF, data=5500004000 ------> 0xFF as event code indicates that this is a Cypress vendor specific event. I don't know what the meaning of this event.
hciEvtProcessMsg: evt=05, data=00400008 --------> Disconnect event with reason 0x08 (Supervision timeout)
DM_CONN_CLOSE_IND, r=0, cid=1 ------------------> Connection close
hciEvtProcessMsg: evt=0E, data=01082000
hciEvtProcessCmdCmpl: 2008
hciEvtProcessMsg: evt=0E, data=01092000
hciEvtProcessCmdCmpl: 2009
hciEvtProcessMsg: evt=0E, data=01062000
hciEvtProcessCmdCmpl: 2006
hciEvtProcessMsg: evt=0E, data=010A2000
hciEvtProcessCmdCmpl: 200A
BLE_GAP_EVT_ADV_START --------------------------> Start advertising again
---------------------------------
As you can see, when the phone is trying to connect to Cypress, the Cypress sent back a vendor-specific HCI event along with the event data (marked as RED above).
I've tried finding on google if there is any document about this event code and event data but no luck.
I doubt that this is the reason why the disconnection happens, as the MCU does not handle this event correctly, thus, there is no communication between host and the Cypress board, which leads to disconnect with supervision timeout.
Could you please help explain what is the meaning of this event and what steps do I need to make it connect successfully?
Thank you very much.

Hi TrDo_2870581,
I see this is same query as that of Issue in establishing connection with CYW43012 (standard HCI mode) , can you please let us know your response on that?
