programming failed

1. Original setup: SK40C ---- UC00A ------ Computer

2. New setup: SK40C ---- SKKCA-21 --------wireless ------- Bluetooth dongle (computer)

If that is the case, have you tested:
computer (USB) ---- SKKCA-21 ------wireless ------- Bluetooth dongle (computer)

test this first, it might be you have yet establish connection between Bluetooth.

test have been conducted according to the manual, and it work. yes, i use the new setup above. just like using UC00A, i just replaced it with SKKCA-21. but using UC00A it worked but SKKCA-21 it failed. i just modified the baudrate in programming, from 129 to 0x0A.

the program i tested it with is the SK40C 16F877A Sample Program. Power switch is ON. its working nicely, its blinking, except that i have to put both USB and and DC adapter on. the Adapter i am using is 12VDC, 500mA. Is there a current requirement for this SK40C? so far, all my program is working but it has to be with the two power supply, the USB and the adapter. i tested the MCLR line. When both usb and adapter are connected and on, when SW0 is pressed, it drops to 0, when released, it reach 4+VDC. when i remove the usb, just the adapter on, when SW0 is pressed, drops to zero but when release, it just goes up to 1.7VDC.

Seems like either the SK40C regulator or the adapter got problem. Can you try with other adapter? Anyway, you can send the item back in order to verify the problem. Please fill in the form on the Support Tab at our website. Our support team will email you the warranty form and please send back together with the item.

would it be a problem if the sk40c i bought is from an electronic shop in KL? Would it be covered by warranty?

Yes, as long as it's still under warranty period.
