PSoC™ 4 Forum Discussions

Hi

I am trying to recreate a similar app. Does any one know what Android components were used to create the tabs?

Hello everyone,

A simple question: How can I power up PSoC 4 using external battery? Instead of using the USB as a power supply, I would like to connect it to batteries.

What type of batteries should be used? What is the suggested voltage and current for the PSoC 4? How are the batteries going to be connected? to which pins? What should I be aware of before I make any connections?/

Please be generous and help me with this.

Thanks,

Solomon,

Hello,

it looks simple but didnt work. I want to add printf for debuging.
I used a sample code from a "BLE_Battery_Level" example project.

I have a debug.c file with the following code.

#include <project.h>
#include <stdio.h>
#include "main.h"
/* For GCC compiler revise _write() function for printf functionality */
int _write(int file, char *ptr, int len)
{
    int i;
    file = file;
    for (i = 0; i < len; i++)
    {
        UART_DEB_PutChar(*ptr++);
    }
    return len;
}

And in my main.h the following

#include <project.h>
#include <stdio.h>
#if (DEBUG_UART_ENABLED == ENABLED)
    #define DBG_PRINTF(...)          (printf(__VA_ARGS__))
#else
    #define DBG_PRINTF(...)
#endif /* (DEBUG_UART_ENABLED == ENABLED) */

I cant find any different setting in the project build settings. But it will not work.

Any idea?

Thanks a lot

Hi,

Checking the Bluetooth Low Energy (BLE) 3.30 component Datasheet, among the GATT Client Functions I found functions to read a characteristic using either its UUID or its handle to define the characteristic you want to read from:

GattcReadCharacteristicValue

GattcReadUsingCharacteristicUuid

But, in the case of writing there is no function available to write to a characteristic using  the UUID of the characteristic as reference. You can only use the handle as reference to define the characteristic you want to write to using this function (among others):

GattcWriteCharacteristicValue

Is there a reason for this limitation, I mean is there a reason for not having a GattcWriteUsingCharacteristicUuid kind of function?

In case I know the UUID of a characteristic I want to write to but I don't know its handle, which is the simplest  and quickest sequence I could follow in order to obtain its handle and be able to use GattcWriteCharacteristicValue? Maybe using GattcDiscoverCharacteristicByUuid?

Thank you for your help.

Hello.

We generated a hardware with a CYBLE-222014-01-Modul.

In the past we took our OUI (company-ID) andour number group and programmed it in the modul. https://dict.leo.org/englisch-deutsch/groupNow I hear, that I must pass through a declaration and I must buy a Declaration ID.Do I need now booth? The OUI with number group and the Declaration ID?If I am usig a module, my hardware must run through the simple declaration process. I have my own profile (with services and characteristics). Is that a simple declaration process also?Thank you.Best regards.Rasmus

Hello, I am working with cy8ckit-042-ble. The data received is displayed in the cysmart tool but i want to save that data into a file. Is there a way to do so through cysmart tool or can i use any other software or tool to save the data?

Our product has the CYBLE-022001 BLE Chip in it.

In the datasheet it's described as a Bluetooth 4.1 "single-mode module ", what does single-mode module mean?

When using this Soc, am I able to adopt BT features from BT Core version 4.2, like Advertising Extensions, LE Secure (DHEC encryption), or the ability to chain advertisement packs together? If I did this, could I then say my product is uses BT 4.2?

I understand most of the BT 5.0 stuff requires a HW update, but I'm getting mixed reviews about 4.2 stuff.

thanks for your time.
