bluetooth rs232-ttl transceiver: wireless ExLink cable :)

[SatTel]

ok, a little extra coffee did it. These back-plane ones don't take AT commands, I got it to the correct baud rate with serial command:

Code: Select all

set baud 115200

Hello

I think I have the same Module, how to get it work?
What is meanet by "serial command"? Connect a TTL Cable and use a Terminal programm, type "set baud 115200", or connect by bluetoots and set this command, or what?

[juusso]

Yes, use another serial cable, not over bt.

Thanks for reply.
I've tried several serial cables and Adapters (Nokia CA-42, DKU-5, Sparkfun FTDI...) I don't get any answer from the BT Module.
I tried At Commands and the set Command with putty 9600,8,n,1 but no reaction.
This is the Adapter I bought http://cgi.ebay.de/ws/eBayISAPI.dll?Vie ... AQ:DE:1123

I`m using another module, but i think principle is same. Here is my experience, i also tried several times and finally got an answer from module just after copy/paste all command at once.

<...>Unlike other units this one accepts command when the are sent within one second. So hyperterm is usesless, use sscom32. DO not send a CR after the command but just the command.<...>

Thanks again but I do not get the damn thing to run.
I built an adapter with a Nokia dku-5 only tx > rx and rx > tx (I don't use the gnd because it cames from the supply voltage and its the same as from the DKU-5), the supply voltage I have connected via a separate USB plug (the module goes from 3.6 - 6V) then I use putty 9600 baud, 8 Data Bits, 1 Stop Bit, no parity, no Flow control and paste by right click AT+BAUD8, I get now answer or Ok. I have also tried to set 4800, 38400 and 57600 Baud in putty and I tried sscom32 with the same result. I'm already on despair
Is it right that after I insert the AT command does not need to press enter?
And what does the LED on the Module if the AT Mode ist present, changed something there?

if this is truth, your back-planed module doesnt support AT commands.

[SatTel]

Ok, finaly it worked.
The problem was apparently the Nokia DKU-5 adapter, now I used the Sparkfun FTDI Basic and thus worked with copy/paste the AT+BAUD8. The Answer from the Modul is OK115200 Hooray, and thanks a lot for you patience, nice that there are so helpful people like you

hurray

Hi to all i want to buy this module because i haven't an exlink cable and i need to format mtd_rwarea but i'm confused because the info in this topic are partial and i don't found info on wiki so i understand that i have to buy this module -->http://dx.com/p/wireless-bluetooth-rs23 ... dule-80711 but I'm noob in doing this things so i need more information and a step by step guide with images... could someone wikifi this method?
i read that this module in better --> http://www.ebay.com/itm/Wireless-Serial ... 1e6bfcc921
but i don't understand i have to sold one use cable?one diode o a voltage regulator????
is there one of this chips ready to use? i'm not good to weld... i mean one that as the voktage regulator and that needs on a usb cable? could someone post picture of the module connected to tv or simple the module with usb cable sold?
thanks in advance.

[juusso]

with this module you don`t need any woltage regulator. just connect it to vga and give +5 volts power. You can feed it from USB, but carefull, dont burn your tv
