Cytron Technical Forum

i bought 2 unit of SKXBee to communicate to each other.

i have the problem where the com port in not detected.?
i have check the baudrate, COM port alr... but still appear this message..
is there solution for this prob?
tq

I think you have email Cytron support and show that it works originally, wireless communication is fine until you perform write firmware operation to XBee module.

Did the write operation success? We did see this symptom sometime, when you rewrite the configuration, the process fail and the firmware on XBee corrupted. And it cannot be recognized as XBee. Reloading firmware is essential to bring it back to normal. Try to use the following guides to reload firmware.

1) Connect USB cable to SKXBee and to computer
2) Lauch X-CTU and set the default setting - COMx(the biggest number COM), 9600bps, 8data bit, no parity and 1 stop bit
3) Go modem configuration tab, select XB24(for XBEE) or XBP24 (for XBEE-PRO)
4) Select XBEE 802.15.4 for function set and 10CD for version
5) Select always update firmware and and show default
6) Press and hold the RESET button on SKXBee
7) Click "write" on XCTU window
8) When action required box come out, release the RESET button
9) The box will disappear and start loading firmware
10) If fail, please try a few time.

It is recommend to change the setting using AT command, as writing firmware will take bunch of data and might cause the process to fail and lead to firmware corruption.

tq.. is there a way for me to save the destination and sender add in SKXBee?

I think using AT command can do it. There is a function to write the data to EEPROM in XBee right? try looking through the datasheet.

do u mean de command "ATWR" which save in the non volatile memory?

at the sender side.. im connecting PC and SKXbee directly.. which i can configure the AT command by typing it...



at the receiver side.. im connecting PIC16 to SKXBee directly... so i need to write the command in the SKXBee rite?

so can i save the the address of the sender's SKXBee in the receiver SKXBee permanently so that i need not type the command everytime.

hope u can guide me..

tq

hi,

yes, u can write the address to the non-volatile memory of the XBEE.
just plug the SKXBEE to the computer and set the correct address and with ATWR, u can permanently save any parameter( including baudrate and any other configurable parameter) u like to the Xbee. do the same to both xbee by using the computer.


rgds,
yh

first i set the address by using ATWR to set the sender's add at the receiver unit through a PC...?

will the add still in the memory when i off and on back?

then i interface it at my PIC without any extra programming?

hi,
ya

atdl xxxx
atmy xxxx
atwr

it will keep the addresses eventhough u had off ur xbee
just try it.

rgds.

tq... i'll try and let u noe the result..

hi there...

it really works...
now i can communicate between both modile straight away
tq
