Psoc 4 BLE standalone broad BLE not work

[chbuc_1650646]

I'm using CY8C4247LQI-BL483 chip (same a kit) for my standalone project. I tested by blink , spi , uart ,i2c,... project and all work ,but  "BLE project not work". I used BLE example project from the kit

   

note. my broad have 3x (1.0uF,0.1uF) bypass capacitor but , kit used 4 for VDDR pin (see my schematic)

   

Thank.

So all these programs worked Blink,Spi,Uart,I2C,ect but it fails to transmit in Ble?

What kind of Antenna are you using?

[chbuc_1650646]

yes sir, all worked but BLE failed .

   

I used antenna chip 2450AT18A100E from Johanson-Technology-Inc.

   

I debug with breakpoint(F5) and use F10 for each line debug but enough to " CyBle_Start(AppCallBack)" line not do anything.

   

Thank You. 
help me please.

Are you using the Ble Dongle to troubleshoot the Ble section of the design? Also your antenna design looks incorrect to what the MFG of the Antenna recommends.  You have the wrong values of parts and the stripline seems to be incorrect in the measurements.  The Striplines need to be very accurate in order to be in the correct frequency.  Also looking at your picture it appears that you have some solder issues in the area of the Feed parts. Did you check the design with a network Analyzer?

Also can you post your program so we can try it out on our equipment.

i using BLE_Battery_Level from example project. kit worked and can blink advertising LED but my board not blink LED or can do other line .

   

CyBle_Start()  not do anything when I debug each code  line

   

Is it possible? if bad antenna design BLE API not work. maybe I think ble can start with bad signal.

   

Thank you

i found it !!!! my 24Mhz crystal PCB footprint incorrect , worked  

   

and i will fix antenna matching circuit for next rev. board

   

Thank You very much "bobgoar" for waste your time.
