SKKCA-21 cannot start, hardware not found

[Bowl]

As the title implies, my Starter Kit, SKKCA-21 is unable to be started. It is stated that the bluetooth hardware is not found.

1. How long is the warranty period if purchased online?

2. What i did?

i installed the driver from http://www.cytron.com.my/attachment/USB%20Driver.zip, and used this software http://www.cytron.com.my/usr_attachment ... 227.10.zip to establish communication. I pressed the reset button but nothing happens and the same message is displayed. Can not start bluetooth. Bluetoth hardware is not found.

I am using Windows XP SP3

BTW, i didn't touch the kit for a year....

[hyng]

Normally the warranty will take 3-4 days depending on the defectiveness of the product.
BTW, does your computer recognize the USB com port for that SKKCA?

[robosang]

I am using this SKKCA for long time ago.... no problem to create connection with the Bluetooth donlge (external). Until now it is still working The picture you posted cannot be viewed.

I think Cytron have different period for warranty, it should be some place in the datasheet or User's Manual.

You are saying the host computer cannot communicate with SKKC through USB or other bluetooth cannot find the SKKC?

[Bowl]

What i did wrong?
I misunderstood and tried using the Bluetooth software http://www.cytron.com.my/usr_attachment/IVT6.2.227.10.zip to communicate with the module.

Does this picture confirms that the SKKCA-21 is working?
I connect using the usb serial port to connect to the module via hyper terminal as the medium.http://www.mediafire.com/i/?7lv8l4okwojb43z

Quoting the manual: Computer A connects to the SKKCA-21 while Computer B uses a BT (Bluetooth Module) dongle.

I only get to confirm that Computer A and B established communication. Do i have to switch on Blue Soleli http://www.cytron.com.my/usr_attachment/IVT6.2.227.10.zip if i were to connect PC (own Bluetooth Module) to PIC16F877A (SKKCA-21)?

Anyone good in assembly code, PIC Basic Pro, C language, assembly language?

I have a favour to ask, what is missing in my PIC Basic Pro Coding below? My question is how do I establish serial communication between a PC and a micro controller?

I am using PIC16F77A to connect to a PC via a bluetooth module but the hyperterminal does not displays anything. Basically, the coding should transfer ASCII character 0, 1, until 9 to the PC when a push button is pressed.

Disclaimer:
The assembly language and C language does not perform the same function as my coding.

Details:
The language used is PIC Basic Pro, Compiler: MicroCode Studio Version 4.0, Assembler: Microchip/mpasm suite, MPLAB IDE v8.66, Windows 7.

Anyone have materials for reference ? I am not proficient in assembly language.

BTW, Cytron provided this coding in C for reference, a DIY project, PR6:

}

What is the receive routine in PIC Basic Pro?

Do I need to include a receive routine if the PIC only transmits data?

What are the interface requirements of the Cytron SKKCA-21?

[Bowl]

For Baud Rate of 115200, is TXSTA = 24 or %00100100 ?

DO i need to set a "if" condition to check whether TXIF = 0 before i transmit via bluetooth?

IF (TXIF = 0) THEN
FOR count01 = 0 TO 9

PAUSE 2000

TXREG = count01 + $30 ' Transmit Data and + $30 s that Hyper terminal can display recognizable ASCII characters

ENDIF


What is the protocol of bluetooth to transmit data?
The reset pin at SKKCA-21, do i have to ground it because i ground it.

Do i need to set the value of register RCSTA if i don't use them because I only transmit data not receiving anything

[Bowl]

so i used http://cytron.com.my/attachment/PR6.zip and to my surprise the PC is unable to establish communication with the SKKCA-21 [paired with PIC16F877A]

I followed steps from http://cytron.com.my/userpage.php?id=PR6 but nothing works.


At step

[3. Setup PC for Bluetooth interface
Next, double click on the symbol of the Bluetooth module. The software will automatically select the method to connect with the Bluetooth device
]

the PC states that it is unable to find any services and it asked me to check if Bluetooth is on or it is connectable....

What did work?

PC A with SKKCA-21 is able to link with PC B with bluetooth dongle. Hyperterminal [PC A] is able to sense when PC B disabled communication.

Hardware Used:

1 Starter Kit (SKKCA-21)
1 20MHZ Resonator
1 PIC 16F877A [Cytron's]

Burner and programmer from Cytron.

Software?
http://www.cytron.com.my/viewProduct.ph ... ve956UfnA=

So I sent a query to cytron at the support tab...

Anyone with a SKKCA-21 can test my coding?

My current coding:

hi..
From the pictures you have upload, the bluetooth icon is unactive and computer not regonize your bluetooth port.
Try to connect bluetooth dongle to your pc and wait untill hardware installation for bluetooth is finish.

[Bowl]

No problem now. BTW, my PIC Basic Pro coding works with Hyper Terminal.

Reminder:

Use BlueSoleil to communicate with the PIC

Spoiler: show

http://www.cytron.com.my/usr_attachment/IVT6.2.227.10.zip

to establish communication. My laptop's pre-installed BT module cannot establish communication with the PIC so i used a random BT dongle instead. Bluesoleil does not recognize the laptop's BT module...

Bluesoleil cannot use SKKCA-21 as its BT medium which answers why Bluesoleil displays these message:

"Can not start bluetooth. Bluetoth hardware is not found."

http://www.mediafire.com/i/?8xi7vcik4kpxdd7

Question:

Anyone have other tested options other than using BlueSoleil to establish communication?
