PSoC 4 MCU

[Anonymous]

Hello,

   

I am using PROC 4 BLE as a central device. I want to exchange data with a peripheral device which is advertising.

   

The API Cyble_gapcconnectdevice() is returning CYBLE_ERROR_OK. Thus api is successful.

   

But CYBLE_EVT_GATT_CONNECT_IND and CYBLE_EVT_GAP_DEVICE_CONNECTED events are not generated eventhough api is successful.

   

What may be the possible faults ?

   

Thanks.

Hi,

   

Are you able to connect the peripheral device with the Cypress BLE Dongle and CySmart App? This is just to ensure that the peripheral device is in a state to accept connection. Please try this.

   

Please check the handshake happening between the central and peripheral using a BLE Sniffer to see what exactly is happening if you have one.

Hello,

   

Peripheral device is connecting using Cysmart app. 

   

Cyble_gapcconnectdevice() says scanning should be stopped before calling the function. I have stopped scanning using the cyble_gapcstopscan() fuction after gap peripheral is located. Then the CyBle_GapcConnectDevice is called. It works perfectly says the api result. 

   

Although scanning is stopped again the CYBLE_EVT_GAPC_SCAN_PROGRESS_RESULT generated which is result of gap peripheral discovery. Also getstate() function shows scanning stste despite of stopscan() function.

   

Also, no generation of CYBLE_EVT_GAP_DEVICE_CONNECTED event after the successful connectdevice call.

   

What may be the possible faults ?

   

Thanks.

Hi.

I encountered this problem too. I use the PSoC example name "Central and Peripheral" and call the function "CyBle_GapcConnectDevice" which return "CYBLE_ERROR_OK". But both "CYBLE_EVT_GATT_CONNECT_IND" and "CYBLE_EVT_GAP_DEVICE_CONNECTED" never show up but "CYBLE_EVT_TIMEOUT" does after 30 seconds.

I have already make sure that the device able to be connected use the Cypress dongle and the program "CySmart".

What may be the possible faults ?  THANKS

Make sure that you are selecting your peripheral device (executing 'z' command ) before sending the connection request (executing 'c' command).
