Do somebody know the PSOC4 BLE UID(User Identification) how to get? Just like the 96 bit the only global ID data about STM32。

Hi,

According to the documentation for the block, the CYBLE_EVT_GAPP_ADVERTISEMENT_START_STOP event should be called when advertisement starts or stops. But if I run my code with the debugger on my CY8CKIT-042-BLE board, a breakpoint in the event is triggered over and over, with almost no time in between. Can anyone please tell me why this is happening ?

I'm using the attached code on a PRoC BLE module. At this point, there isn't much of my code left. The only thing on my TopDesign schematic is the BLE block (v2.00).

I've been studying the API documentation and the 100 projects as well as trying some experiments with my own custom service. I'm puzzled by the typical code for handling write events when a custom characteristic supports both read and write. Typically in the 100 projects it is something like:

case CYBLE_EVT_GATTS_WRITE_REQ:
case CYBLE_EVT_GATTS_WRITE_CMD_REQ:
  wrReqParam = (CYBLE_GATTS_WRITE_REQ_PARAM_T *) eventParam;
  if(wrReqParam->handleValPair.attrHandle == MY_HANDLE)
  {
     CYBLE_GATT_HANDLE_VALUE_PAIR_T hvp;
     uint8 theValue[2];
     theValue[0] = wrReqParam->handleValPair.value.val[0];
     theValue[1] = wrReqParam->handleValPair.value.val[1];
     hvp.attrHandle = MY_HANDLE;
     hvp.value.val = theValue;
     hvp.value.len = 2;
     /* Report data to BLE component for sending data when read by Central device */
     CyBle_GattsWriteAttributeValue(&hvp, 0, &cyBle_connHandle, CYBLE_GATT_DB_LOCALLY_INITIATED);
  }

Three things puzzle me about this:

    
1. Why is it necessary for application code to write the received value to the database? The API description (and common sense) implies that the stack should do this automatically subject to permission settings.
    
2. Why is it necessary to copy the handleValPair? Why not just specify '&(wrReqParam->handleValPair)' as the first parameter to ..WriteAttributeValue?
    
3. Why is the last parameter to ..WriteAttributeValue ..LOCALLY_INITIATED rather than ..PEER_INITIATED when we are responding to a peer write? As far as I can gather from the documentation this will bypass server permission settings.
   

Anyone have any insight into this as it is really baffling me!

In the example project SCB_SpiCommMaster there are two SPI components, the SPIM (master) in SCB mode and the SPIS (slave) in UDB mode. My question is: 

How did the internal pin of SPIM \SPIM:miso_m\ get connected to the external pin P0[1]?

Is there any help file or video clip explaining this step of configuring/routing the SPIM to SPIS?

How can can I get a 100ns-increment counter in PSoC 4 BLE for the purpose of time-stamping data samples?

Using a UDB counter, the system complains about clocks and such.

Accelerometer data is acquired via I2C with an interval of about 3.8 ms between data sets. (this is now working)

The "time" is to be read out of the counter and applied to the current data set as it begins to come in.

The data sets are to be shipped to a cell phone via BLE. (this is not working yet)

A data collection run will be a few (maybe 10 or so) minutes long, during which the time stamp generator needs to run without glitches.

How can I make the 100ns counter?  It is mainly a question about sources for "count" (10 MHz) and "clock" inputs.

I've used this time stamping plan on other micro controllers, including PSoC 5 (FirstTouch in 2011).  Creator 3.2 messes up the TopDesign picture, so I can't view the design info there due to missing obsolete components.

Thanks.

Hello Cypress Community!

I am working with a PSoC 4200 BLE kit and trying to use 2 SCB blocks to configure 2 different UART connections. I want to have one be TX+RX and the other simply be TX. 

I am having quite a bit of difficulty getting them to work.

Is it possible to have 2 UART connections?

Thanks
