Bluetooth Modem - BlueSMiRF Silver???

Wireless & IoT
1

I got this module. Hooked it up to a GPS receiver chip. I see the red LED is on and I have 5V supplied to the Bluetooth module. However, my PC refuses to detect the Bluetooth device.

Has anybody gotten one of these to work?

Here’s a link to the device:

Yep, I managed to use the Bluesmirf silver. Although in another setup, I connected 2 of them together as a ‘wireless link’. Although I tdo have problems using them on 5V, looks like they don’t start-up very well. On 3V3 I have no problems and for my application thats fine.

Be sure to use the right command set (http://www.sparkfun.com/datasheets/Wire … rGuide.pdf) because the gold version seems to have a complete different command set. Follow chapter 9, best setup for testing is to have 2 modules connected to one pc with terminal windows. Keep in mind the module has to be setup to be a server AT+BTSRV=1 before you can reach them by air. When a link is established, the green led will be activated.

Oh, and be sure you have the correct baud rate talking to them. I am almost sure it is 9600 baud but its not mentioned in the bg203 description

How far did you come with this ?

I thought it would be seemless. Just plug it in and it would go :wink:

Silly me. So I have to write a sort of boot up script to initialize the connection?

Do you have some example code I could give a shot? It’s plugged into my Arduino aat the moment.

I’m reading chapter 9 and looking through the manual. They don’t explain much here. I’m assuming these setting strings are transmitted over a serial bus at 9600 baud?

Thanks!

Well first you have to setup the modules, sometimes they do it automaticly but I think these ones don’t. Indeed, its 9600 baud. Sorry but you have to study the commands, use the AUTH command (BTAUTH or something like that) to tell your module to connect automaticly, once you did this they are setup and next power-up they connect automaticly. Sorry I have no more information for you now, but search this forum, I saw someone who write software in vb.net to do the module settings for you.

Good luck

i’ve sent

AT+BTCFG = 32

the response is “OK”

then

AT+BTSRV=1

i got “OK” also

l also had changed the local device name with AT+BTLNM, the baudrate setting is OK

but i still can’t see my BG203( WRL-08469)

(phillip) in my bluesoleil device search

is there any other command to broadcast the bluetooth

module…?http://www.sparkfun.com/commerce/produc … ts_id=8469

is it broken or … i just miss something

thanks for any reply… in advance
