PSoC™ 4 Forum Discussions

In sample projects many of it have this text:

On an advertisement event timeout, if the device is not connected to any Client, the device goes to the Low Power mode (Hibernate mode) and waits for a SW2 button press to wake up the device again and start advertising.

but Sw2 not have interrupt handler and when user push button program make restart. I see for example in BLE_Battery_Level this message :

"BLE Battery Level Example Project " that placed in start of code.  

How make that device will be real wake up ( advertising without reset) ?

Hi,

     I have a project I am working on for my company.  As part of this I am required to save the project in a Subversion repository so it can be part of the deliverables for the whole project.  I would like to know what files of the project should I save in Subversion ? Then when someone else pulls that revision they can build the project.

     Would this be enough ? Or too much ?

    
• TopDesign\TopDesign.cysch
    
• <ProjName>.cydwr
    
• ​<ProjName>.cycdx
    
• ​<ProjName>.cyfit
    
• Header file directory
    
• Source file directory (with all my added C/H files) and main.c
    
• <ProjName>.​cydsn​
    
• <ProjName>.cyprj.<my name>
    
• <ProjName>.rpt
    
• <ProjName>.svd
    
• cyapicallbacks.h
   

Thank you very much for the help.

can anyone help to convert PSoC 4 BLE Module (brd file) into altium designer.

best regards

Hello there.

I am now searching the RF IC which outputs I/Q signal to get phase data for calculation.
It would be common for this purpose to use I/Q demodulator and microcontroller,
but these are too expensive to use for mass production.

I am searching widely used IC which outputs I/Q signal and inexpensive.
I know a few IC which outputs I/Q signal, but I can't find it because there is no description about it in datasheet.
Moreover, it also needs microcontroller.

So, PSoC is the best if RF part of it outputs I/Q signal by reason of  single chip configuration.
Though I can't find setting to output I/Q signal from this BLE module used in PSoC Creator.

Are there any PSoC and RF module which I can get I/Q signal and calculate phase value ?

Hi guys!

At the moment i am working on a project that should enable a Android Device (APP programmed with Java in Android Studio ) to send a picture to the CY8CKIT-142. I used a MTU size of 23 bytes because of another Problem which i want do discuss in another post. Because of the resolution of the Eink-display i have to send 284 - 23 byte packages. It takes about 28!!! seconds to transmit the picture. Is there any way to speed up the transmission?

    
•  MTU size is 23byte;
    
• Profile role: GATT Server
    
• GAP role: Peripheral
    
• BLE low power mode
    
• Custom Service 16 bit and Custom Characteristic with 16 bit ->
    
• variable named DATA Type: uint8[]; Length = 20 byte
    
• Properties of Custom Characteristic: Read is true and write is true
    
• GAP Settings -> General -> Attribute MTU size = 23bytes
    
• GAP Settings -> Peripheral preferred connection -> Connection interval Minimum = Maximum = 7.5ms
   

a few lines of my Code (only write request in StackHandler of BLE)

case CYBLE_EVT_GATTS_WRITE_REQ:
        wrReqParam=(CYBLE_GATTS_WRITE_REQ_PARAM_T *) eventParam; /       
        if(wrReqParam->handleValPair.attrHandle==CYBLE_DISPLAYAKT_DISPLAY_CHAR_HANDLE)
        {
            if(CYBLE_GATT_ERR_NONE==CyBle_GattsWriteAttributeValue(&wrReqParam->handleValPair,0,&cyBle_connHandle,CYBLE_GATT_DB_PEER_INITIATED))  
            {   
               for(i=0;i<MTU_SIZE-3-1;i++)
                {
                    picture[i+(MTU_SIZE-3)*packagenr]=wrReqParam->handleValPair.value.val;
                    //receive++;
                }                
                CyBle_GattsWriteRsp(cyBle_connHandle);
