Sending Data from a Bluetooth Module to a Cell Phone

Wireless & IoT

Hi, I am trying to send a message from a bluetooth module to a bluetooth enabled cell phone without modifying the cell phone’s “software.” I have read a few message board posting regarding sending bluetooth messages the other way (phone to module) but I have not been able to find a step by step procedure to send data directly from the module to a cell phone.

Does anyone have any information on how I might achieve this?

Right now I am using the WRL-00148 module.

Thanks.

What do you want the cell phone to do when it receives the message?

You might be able to do OBEX PUSH over RFCOMM, assuming your bluetooth device lets you make an RFCOMM connection to an arbitrary channel on the other device (I haven’t used the WRL-00148).

Hi Wiml,

I was hoping you’d respond. I just want the phone to display the message (it could even receive it as a business card file if necessary). Ideally the phone would take the message and forward it as a text message to a given phone number, but I’m pretty sure that can’t be done without installing a java midlet on the phone.

Here is my command set: http://www.sparkfun.com/datasheets/RF/B … .1.4.0.pdf

It looks like sections 4.3-4.3.2 are referring to the OBEX Push procedure you mentioned. I’ll test this out as soon as possible and report back.

Thanks.

By the way, from an early post I read that: http://www.benhui.net/modules.php?name=Bluetooth is a very good resource. The site no longer seems to be in existence, does anyone know of a comparable resource for bluetooth?

Yeah, that looks like the kind of thing I was thinking of :smiley: I didn’t know that it had specific support for doing object push, that’s convenient! I haven’t tried doing OBEX from a microcontroller project yet. I’m curious to hear how it works.

i remember reading something about running a standby java application in background, if u combined that with a phone that allowed java to use serial port profile this could be really easy

This sounds like an interesting idea, but I’m not following you 100%, could you provide a little more explanation?

my phone mentions the ability to set a standby app, however after some searching i have not found anymore about this

I found an article about creating a Standby Midlet to run on a mobile phone: http://developer.sonyericsson.com/site/ … phones.jsp

How are you thinking I would be able to use this standby application?

java on the newer phones have to ability to use bluetooth, including the serial port profile, all the standby app has to do is keep the link open and wait for new data

Alright, thanks for the suggestion.

I’ll let you guys know how this all works out when I get a chance to test it.
