How I can do to make complete data can be transmitted ?. Because sometimes not transmitted by completo.Ver figure and program

Hello

I am new to cypress and am very exited to make my first custom ble profile.

I need to send 3 datasets that i capture from three sensors attached to the ez-ble module.

What is the best profile i can setup:

>Do i need to put each variable to a separate service?

>Do i need to have one only service and get 3 charcteristics for it which are the sensors values?

>Is the CYBLE_EVT_GATTS_WRITE_REQ event triggered when i have "write" or "notify" property in the characteristic?

One other important thing:

I have a temperature stored in int32, when i try to  write to the GATT database :

CYBLE_GATT_HANDLE_VALUE_PAIR_T tempsensorhandle;
                tempsensorhandle.attrHandle=CYBLE_TEMPSENSOR_TEMPSENSOR_SENSING_CHAR_HANDLE;
                tempsensorhandle.value.val=temperature;
                tempsensorhandle.value.len=sizeof(temperature);
            gattError= CyBle_GattsWriteAttributeValue(&wrReqParam->handleValPair,0,&cyBle_connHandle,CYBLE_GATT_DB_PEER_INITIATED);

I noticed that tempsensorhandle.value.val is an *int8 which cannot store my int32 temperature although i have declared it in32 in the ble configuration interface. Do i need to get every 8bit of my 32 bit integer to store it there?

I use the demo projcet, the BLE_HID_Keyboard project.
First step, i program the project into the demoboard(CY8CKIT-042-BLE).
Second step,when the demoboard runs, it will advertising.
Forth step,i used the an android phone to connect the demoboard ,and it is successed.
Fifth step, i disconnect the link, and the i program the demoboard again, so there is no bonding key on the demoboard.
Sixth step, i reconnect the android phone to the demoboard , it is failed. But there is no CYBLE_EVT_GAP_AUTH_FAILED event.
So how can i get the CYBLE_EVT_GAP_AUTH_FAILED event when the ble authentication failed?

The builtin chip in my psoc-4 development board (25$) got shorted out. I changed it with a new one.

Now this chip is not being programmed. The device is being shown in the programming window, but it says " The target device is already in use by another client" and also there's another message "The device was recognized. But Creator does not support programming it at this time"

Please help

Is it possible to use PWM whilst the processor is in deep sleep? i.e setting up PWM whilst the processor is active and then leaving it running?

Hello

what is use of two API

RTC_SetAlarmMask()

RTC_GetAlarmMask()

actually I am trying to compare current time and alarm time. If alarm time and current time match ,alarm occur.  If both time does not match , no alarm occur. I am not sure but I think I have to use  RTC_GetAlarmMask(). so that we can compare both time 

Hey guys,

following situation: I have a blood pressure device that I want to read out. Currently my firmware connects to the device and I am able to read out some device information using the UUIDs given in the SIG and CyBle_GattcReadUsingCharacteristicUuid API. I'm not able to sniff through the device using CySmart. Therefore I don't know any handles. Is there a way to receive them using the PSoC Creator?

Currently I'm working with the PRoC.

Thanks for your help.

kind regards

Lars
