AIROC™ Bluetooth Forum Discussions

Hi Infineon team,

Hope you are doing well.

I would like to know the total internal inductance and capacitance of CYBT-343026-01. This is needed for 'Intrinsic Safety'  application, and is a requirement to be given in the document.

Kind regards,

Remo

Hi together,

I have the CYBT-213043-EVAL connected to the MiniProg4 connected via the SWD pins and followed the instructions on 

https://github.com/Infineon/btsdk-docs/blob/master/docs/BT-SDK/AIROC-Hardware-Debugging.pdf

I validated that the HW has been setup correctly, as mentioned in chapter 5.1

Then I started the Modustoolbox and clicked on the "Attach_KitProg3_Miniprog4" button to start the debugging. As mentioned in the above pdf, I can click suspend and the break point hangs in BUSY_WAIT_TILL_MANUAL_CONTINUE_IF_DEBUG_ENABLED() loop. Then I set the variable "spar_debug_continue" to 1 and click on "Resume". Sometimes the next break point is hit, but in most cases I just get an error message and debugging does not work:

Error: [CYW20819A1.cpu] Can not find free FPB Comparator!
Error: can't add breakpoint: resource not available

How can I overcome this issue?

Hi forum!

I am in trouble. I have connected my BT module and downloaded makefile by using wiced studio (Look at the screenshoot).
I have to verify that the puart of the module work! I need to communicate with the module by using my smartphone galaxy s3 and receiving on the serial the word "hello" sent by the module. How can i do? There is an application already written?
I need also to try to communicate eventually with PC UART which terminal software i have to use on windows 7?

My module is connected thorugh the uart usb bridge and the firmware download works!

I don't know wich app or which maketarget i have to use! I am totally new on programming and on programming bt module by infineon!

I would like some advice about the layout of the PCB where CYBT-343026-01 is mounted.

(1)
Should the GND plan of CYBT-343026-01 and the GND plan of the MCU be connected with a wide and large GND?
Or should each GND plan be separated and connected at only one point using, a 1.6mm x 0.8mm chip resistor(for example)?

(2)
Do unused pins of CYBT-343026-01 need pull-up or pull-down processing?
Is it okay to leave it as N.C (open)?
*The following Pads are not planned to be used.

Pad 2, Pad 4, Pad 6, Pad 8, Pad 9,
Pad 10, Pad 11, Pad 12, Pad 14, Pad 15,
Pad 17, Pad 18, Pad 19, Pad 22, Pad 23

Please guys i am trying to develop a code for writing on the uart pin RX and TX the Hello word and watch it on teraterm but i fail and no able to understand why. The code is this for the module 413034-02 what is wrong? I have to write repetly hello on the terminal:

#include "wiced_bt_dev.h"
#include "sparcommon.h"
#include "wiced_hal_puart.h"
#include "wiced_platform.h"
#include "wiced_bt_trace.h"
#include "wiced_hal_gpio.h"
#include "wiced_bt_stack.h"

Hi! Community
I purchased the CYBT-413034-02 chip without the EVAL board. Can it be programmed without the EVAL board? I have an UART to USB converter available at home, but I'm not sure if it's suitable. For now, I've only soldered the TX and RX wires and power supply because I need to test if it interfaces with a processor's UART. What else do I need to do to download the firmware into it?
