Broadcasting Radiowaves? - Android Q&A, Help & Troubleshooting

Okay so I did research on this a while ago when trying to develop a broadcast application for music but I couldn't find much. My brother just threw an idea at me for an app and it has me curious again. Many devices are out there for broadcasting to an open FM frequency on a radio to play your music through, such as the Motorola Roadster. But all it does is connect your device to the radio frequency for broadcasting on the certain frequency you pick. I have never seen an app that allows an Android to broadcast at an FM frequency, only Radio apps to receive FM frequencies.Does anyone have any information on the capabilities of broadcasting FM frequency from an Android device? The idea is to develop a Ski beacon application. Currently, beacons are sold for backcountry hikers, skiiers, and snowboarders to be able to transmit their location to other beacons on a specific frequency of 457 kHz. This is not GPS mind you, it is radiowaves. I am really interested in helping figure out various uses of broadcasting radio frequency if possible. Thanks for your answers.

Radio frequencies

It it possible to listen to the radio with your XDA? Not sure if you need extra hardware to execute radio frequencies. Or is this based on software interaction?
You won't be able to use the xda as a radio set to directly receive FM/AM broadcasts.
It should, however, be possible to listen over the internet via a website, but I haven't tried this myself. I've also no idea what this would do to your data tariff.

Streaming over GPRS really does work when you use the correct client. one that is optimised for GPRS.
The RealOne player for Pocket PC is excellent (if you configure it to a 42k codec stream by fooling it into thinking you have a 6 timeslot device). http://www.real.com/realonemobile/download.html
The Windows Media Player is very poor in comparison with frequent and long interruptions.
The problem is that the READY timer that governs radio resource allocation is reset in the downlink be sending packet in the uplink. If you are using UDP then a dumb client would never send anything in the uplink and your radio connection would timeout after 60 to 120 seconds (depending on how clever the Radio Engineers are on your network).
A smart client will send a packet (anything really, but you can do some bandwidth optimisation stuff with it if you like) every 30 seconds (minimum realistic READY timer) to make sure the downlink radio connection is not released.
yo ucan get WMP to work OK if you run a constant Ping applicaiton in the background if you don't believe me... :lol:

Request - cracking and open the radio chip in X7500

The usage for X7500 radio chip beside of FM radio is for GPS navigation usage, the new navigation software versions use TMC for calculating the rout in case of trafic (IGO/MIOMAP/Destinator/TOMTOM).
For using the TMC - radio reciver needed...
It can be an advance feature for X7500 users world wide...
TMC - Trafic Message Channel
The Traffic Message Channel (TMC) is a specific application of the FM Radio Data System (RDS) used for broadcasting real-time traffic and weather information. Data messages are received silently and decoded by a TMC-equipped car radio or navigation system.
Thanks in advance.
im intersted too, but dont have the ability to unlock the radio !!
yes please to radio
I would like the radio function as well to listen to radio 4. unless someone has worked out how to make the listen now option work on the Ameo.
I am ready to donate, is anybody want to join me ?
I will donate as well.

The X7500/01 Don't support this Radio protocol. It doesn't even have an FM Radio tuner.. Just give it up.
others disagree
There are several other posts that say the radio is on board but not enabled. Do you have specific knowledge? can you refer to your source?
Look at the pix and details posted about the chips in the X7500 on the internet. The radio chips used do not spport FM recption.

I've had a look and you might be right !! can anyone confirm for certain that the X7501 has an FM radio !!!

Bluetooth problems with Holux 240 GPS BT Serial

Current Setup
1. Hard-SPL-240-MFG.exe
2. titan_radio_3.27.00.exe
3. dcd_titan_kitchen_2.3.2.rar
Everthing works with some data issues when downloading large files due to a but in the titan_radio_3.27.00.exe (I can live with it).
The problem is when I partnership the Titan with the Holux 240 GPS external Bluetooth GPS it does not connect. I can see the device but never can connect, Yes I use the standard 0000 passcode. Other Bluetooth devices ie my headset Moto N700 and car head unit Sony BT-2500, audio and hands free all work. I'll be travelling to an area with no Digital service and would like to use the GPS with Navigation software.
When I restore the original TELCOM ROM, I have no problems with Holux 240, Moto N700 and Sony BT-2500. When I connect I see a serial port as a list service.
Some threads talk about a fix for the Bluetooth stack? nueROM or Dogguy in PPCGeek.
Another item to be noted. With Bluethooth A2DP headsets, if I connect once do I have the reconnect to the device again? The Sony BT-2500 pairs with with Titan (any CE ROM) but I need to resave the audio everytime.
I haven't tried my Holux GPSlim 240 with any of the new ROMs yet, but I'll try to remember to give it a shot when I got off work.
I'm curious though - why would you want to use external GPS when you can use the one built into the phone? My Titan's GPS seems to be more accurate than my Holux 240. You don't need digital service to use the GPS, unless you're using Google Maps or some other program that downloads maps on the fly. If you already have a navigation program with maps, just use the built-in GPS.
I thought the GPS chip in the Titan was a gpsOne that uses digital cellular signal from the towers to triangulates your position.
From phonenews.com
Installing this update will enable GPS to function inside your HTC Titan. It enables the gpsOne chipset in your device to function as a standard GPS device, compatible with Windows Mobile 5 & 6 GPS applications, including Google Maps, Windows Live for Mobile, and navigation software such as TomTom Navigator. Keep in mind that gpsOne is not autonomous GPS, you will need to have home network coverage in order to maintain a GPS lock.
I posted about this same problem with my Holux 1200. The internal GPS always takes 5+ minutes to connect for me no matter where I am or what I use to juimp start it, so there are times when I'd want to use my external receiver for a quick connection. When setting up my receiver I set the outgoing COM port to 0. Then from the external GPS settings I try to set the GPS hardware port to 0 also, but the setting doesn't stick. It always reverts back to the default which is none. Some people have told me that they never set the GPS hardware port, but I always had to previously to use my GPS receiver. Now with the internal GPS enabled I can't.
Found some more information
gpsOne can operate in 4 modes:
Standalone - Your handset has no connection to the network, and uses only the GPS satellite signals it can currently receive to try and establish a location.
MS Based - Your handset is connected to the network, and uses the GPS signals + a location signal from the network.
MS Assisted - Your handset is connected to the network, uses GPS signals + a location signal then relays its 'fix' to the server, which then uses the signal strength from your phone to the network towers to further plot your position. You can still maintain voice communication in this scenario, but not 'Internet/Network service' ie Web Browser, IM, streaming TV etc..
MS Assisted/Hybrid - Same as above, but network functionality remains. Normally only in areas with exceptional coverage.

[Q] Broadcasting audio over LAN to multiple smartphones with NO LAG

I'm looking for a solution to stream audio to multiple smart-phones without lag.
Can this be done?
Using a laptop (win/mac) as a broadcasting station with WiFi connected.
Is there a limit to the connected clients in a Wifi Router?
Can LAG be minimised?
FM transmission is not a direct option, because it's illegal to do. Although most smart-phones have a FM radio and this option produces no LAG.
This is a project to supply listeners to a small open air concert with the direct audio feed, without the use of central amplifiers.
