PSoC™ 4 Forum Discussions

This problem does not involve any Cypress Kits or the programming/configuration of the BLE 4.1 device.  I have scoured the forums but found nothing that might answer this.

I have a sealed third-party BLE device which apparently uses the EZ BLE part number CYBLE-022001-00 which is supposed to be BLE 4.1 compliant, yet when it is advertizing I am unable to discover it under Windows 7 with several different BLE 4.0 USB dongles (eg. CSR 8510).  Also it is not discovered by and Android 4.3 phone (Galaxy S3). However it can be discovered by a Toshiba Satellite laptop (integral BLE 4.0) and most newish Android phones and iPhone 5.  I know the BLE 4.0 USB dongles on the Win7 PC are working because they can discover the Android 4.3 phone and the Toshiba Satellite laptop BLE.

I was under the impression that BLE 4.0 (Smart ready) and BLE 4.1 are compatible, so should be able to discover each other when made discoverable.  Why can't a BLE 4.0 USB dongle discover the CYBLE-022001-00 BLE 4.1 device?

Hi everyone,

CYBLE_EVT_GAP_DEVICE_CONNECTED  This event is generated at the GAP Peripheral end after connection is completed with peer Central device

CYBLE_EVT_GATT_CONNECT_IND             This event is generated at the GAP Peripheral end after connection is completed with peer Central device

I use both of them  Server-Client application. I analyze with debug. When the connection is established,  enters in two event.

    
• What is difference CYBLE_EVT_GATT_CONNECT_IND and CYBLE_EVT_GAP_DEVICE_CONNECTED events?
    
• What are the drawbacks of using both of them?
    
• Which should I use ?
   

I have followed the AN97060 PWMExample instructions for building a fixed-stack OTA sample application. There appeared to be two fixes required - (1) main.c: missing underscore in "OTA_Optional.h" (2) ota_optional.c: missing definition of mainTimer. After making these fixes the project built successfully.

I am installing on a standalone CY8CKIT-142, without a CY8CKIT-042BLE baseboard. I am using CySmart 1.2 and a CY5670 dongle to test.

CySmart successfully scans the device and allows me to start an OTA upgrade. The upgrade fails on the last step (transfer firmware image).

The serial debug output is:

Hello,

I am developing a product using the CY8CKIT-143A module, but the datasheet says "The CY8CKIT-143A module is intended for development purposes only. Users are advised to test and evaluate this module in an RF development environment. This module is not a fnished product and when assembled may not be resold or otherwise marketed unless all required authorizations are frst obtained."

So I am not allowed to use this module, but is there any alternative module which is compatible? Maybe this one: CYBLE-224110-EVAL? I don't need pin compatibility, as long as the code is compatible and only has to be recompiled. I read that this module is certified too, but I don't see anything about using it in a final product.

And if I use any pre-certified Bluetooth module, do I have to register and pay the Bluetooth fees?

Thanks in advance.

So I'd REALLY like to keep my bonding information after an OTA update but invariably I get INSUFFICIENT_ENCRYPTION_KEY_SIZE when I try to pair after OTA.  I assume some key information or bonding data is getting lost. I'd happily save and restore whatever is getting lost but I'm not having any luck there.  I've tried saving and restoring all the key data but apparently I'm not doing this correctly or I'm missing something entirely.  I'd greatly appreciate any help, hints or suggestions.  Thanks in advance!!

Hello

I'm using actually PSOC4 CYBL10573

I integrate a self flash test which verify the CRC value of flash periodically.and  want to find a solution force the board shut down immediately in case of a wrong CRC Check of flash. My question if there is some registers which could configure the microcontroller to shut down

Best regards

The code immediately below works fine.  The value "5"  is successfully written to the characteristic:

uint8 tilt_0 = 5;

tilt_0_Handle.attrHandle = CYBLE_MYSERVICE_TILT_0_CHAR_HANDLE;

tilt_0_Handle.attrHandle.value.val = (uint8 *)&tilt_0;

tilt_0_Handle.attrHandle.value.len = 1;

CyBle_GattsWriteAttributeValue(&tilt_0_Handle, 0, NULL, CYBLE_GATT_DB_LOCALLY_INITITATED);

CyBle_GattsWriteRsp(connectionHandle);

But when the following substitution is made for the value "5" in the first line, the value of the pin (which can be either 1 or 0) is not written to the characteristic:

uint8 tilt_0 = MyDigitalInputPin_Read();

I've also tried writing the output values from the scanning comparator with no success.

Am I using the wrong data type for the pin read? 

Thanks.

Hi,

I have a system values characteristic that is being read by an android app.  The characteristic delivers the correct values when the PSOC notifies the app, but when the app reads the characteristic, it shows up as whatever values are in the component in PSOC Creator.  Am I writing to the GATT database incorrectly?  Below is my update code.

// Sends notificaiton of sysValues change to the app
void NotifySysValuesChange()
{
    // Set up value structure
    struct valsStruct{
        uint16 angleLow;
        uint16 angleHigh;
        uint8 mode;
    } tempStruct;
    
    // Gather system values and update GATT database
    tempStruct.angleLow = dataLocal.angleLow;
    tempStruct.angleHigh = dataLocal.angleHigh;
    tempStruct.mode = dataLocal.mode;
    CYBLE_GATT_HANDLE_VALUE_PAIR_T tempHandle;
    tempHandle.attrHandle = CYBLE_ROTARYACTUATOR_SYSVALS_CHAR_HANDLE;
    tempHandle.value.val = (uint8 *)&tempStruct;
    tempHandle.value.len = sizeof(tempStruct);  
    
    // Update Gatts Server
    CyBle_GattsWriteAttributeValue(&tempHandle, 0, &cyBle_connHandle, CYBLE_GATT_DB_LOCALLY_INITIATED);    
    // Send notificaiton if authentication is complete
    if(deviceConnected){CyBle_GattsNotification(cyBle_connHandle,&tempHandle);}
}
 

Once again, the notification delivers correctly, but reading the database does not reflect the update.

Please let me know if you have any ideas.  Thanks in advance,

Tom
