PSoC™ 4 Forum Discussions

In my BLE profile I want to use uint16 and sint16 characteristic values as well as uint8.

However, the provided  function "CyBle_GattsWriteAttributeValue(..)" uses attribute values that are only defined as type uint8.

Can I use uint16 values or do I need to restrict data to a uint8 and cast/shift into 8 bit values as needed?

Hi, this is Gaurav. I'm doing the I2c Tx project from the 101 videos. I did it several times but I'm not getting the ack signal after transmitting the protocol from the bridge.

I've attached the project file below. Please give the solution and explanation so that i could understand the things.

I'm using PSoC Creator 3.3. and Psoc4-042. Working on the BLE project with led blinking. I'm facing error from the clock and PWM at the 100Hz frequency. The error window is attached in the files. Please kindly look after.

This error is not only is this program, I'm facing this error in every program i was doing at 100Hz Hardware handling. 

Thank you

In Cypress doc  I see this :"The BLE SIG recommends using a 128-bit UUID, different from the base UUID, for custom attributes to ensure that it does not conflict with existing UUIDs for standard services." 

How can I select UUID to ensure that it does not conflict with existing UUIDs for standard services?

Basically, I have a EasyVR Shield and I want to do voice control on PSoC 4(CY8CKIT-042-BLE) Pioneer Kit. I tried to find tutorials of how to integrate the two things and coding for the operation, but so far I have little progress. Anyone please help me out, thank you!

This might be more of a C programming question, but, in my app, when a device is scanned, there are several bytes in the CYBLE_GAPC_ADV_REPORT_T advReport->data (The advertisement packet) that need to be picked out in order to be directed to the next step.  I know the simple way of just looking at each byte in the array, but I want put it all in a struct, and just the necessary bytes.  For example, if a device includes the Service UUID (32-bit) + Service Data, which bytes are in advReport->data[16]-[22]: how can I put those in

struct scannedData {

    uint32 serviceID;

    uint8* serviceData;

}newScan;
