Can i use only CY8CK-037 without CY8CK-042. Because i have only CY8CKIT - 037 . I'm newbie for this topic, Thx.

I have written basic code for reading x,y and z axis data from ADXL362 accelerometer using SPI protocol.Following are the problems I am facing while using SPI protocol with PSOC4 BLE ki(CY8C4247LQI-BL483):

1.when SPI is used in Byte mode with Rx buffer size set more than 16, then SPI won't work and data is not received from ADXL362. If Rx buffer size is less than or equal to sixteen than program works and data is received.

2.If I change pin configuration as mentioned below in the same program then SPI won't work even if the Rx buffer size is less than or equal to 16.

P4.0=SCB1_SPI_MOSI[0]

P4.1=SCB1_SPI_MISO[0]

P5.0=SCB1_SPI_SS0[0]

P5.1=SCB1_SPI_SCLK[0]

I have attached code below please help.

I'm using a CY8CKIT-042 in my design.  ALL my I/O is used for other purposes (LCD, SPI, LEDs and the such).  How can I detect the voltage of VDD with only internal resources?  This is to allow me to set the contract % for the LCD.

Hello,

I am using CYBLE-212019 and am scanning i-beacons the least strength of the beacon I can detect is -79 dBm. I have never saw an RSSI level weaker than this. Is this the least it can detect?

Thank you

Is it possible to access the number of bytes in a characteristic that was set in the BLE GUI but using API code?

Hello,

I am interested to use the PRoC module for indoor navigation system. I recently get to know about RTLS features which can help to build the BLE accurate localization system. Question if the PRoC or any BLE module from Cypress can support this feature and if yes if there is any manual how to implement it.

Thank you so much in advance

I have two BLE devices, one as central and one as peripheral. For the central device, I have the box checked to generate the mac address from the die. I have a need to read the full mac address of the central device within its firmware. Where do I find the mac address within all of the header and source file generated in the BLE library.

Secondly in the peripheral, I assigned an advertising name through the design block of the BLE module. I would like to change that name within the peripheral code so I can either add to the existing name or change it completely. Basically have a default advertising name then change to something else once some settings are established. I thought I found the data for this but everytime I build the code, it defaults back to original data in design block. How can I change the adversting name within the firmware?

Lastly, are there any good references or examples how to set up pin usage between an app and the peripheral device. I have a different project that requires usage of a pin and not sure how to implement.

Hi,

I got a problem with my Psoc. I have CY8CKIT-049-42XX Prototyping Kit. I recent have started programming and I was watching the classes in Cypress's Youtube Channel to learn more about it. I did all lessons and everything it was ok until there.

But, last wesdnesday  I put my psoc in computer and tryed program via bootloader and I coudn't do this. It doesn't enter in "program mode" anymore when I press the switch buttom before connect in  my computer. I searched in internet, but i didn't see anything about it. I check wih a multimeter and switch button it's ok, the voltage levels it's ok too. I don't know what more do and how I can solve this. Pls, help me.
