How to tune a FM radio station

[Guest moneytoo]

Possibly only for Android 2.1 (build 8105). Wired headset must be connected - radio uses it as antenna.

It requires root (so don't forget to run "su"). Run directly from Terminal Emulator, make a script in GScript or wait for someone to make GUI (XsCode made one - http://android.modaco.com/index.php?s=&amp...t&p=1421228).

There's one problem - there's no way how to change the radio volume from the Android OS. It will probably require more low level access.

Turn on FM radio

fm_hcitool 1

Turn off FM radio

fm_hcitool 11

Tune a station

fm_hcitool 3 xxx

*xxx = channel 880 to 1080 (88.0 to 108.0 MHz) Scan all stations

fm_hcitool 10

*Results are saved to /data/fmrssi.txt Change/lower the volume

??

I don't know.

[Guest Reecemac]

fm_hcitool *

replace * with the number:

1 Turn on FMPower

2 Turn on RDS FMPower

3 Set tuning mode as preset mode: parameter 1 ==> tuning ferquency

4 Scan channel

5 Read rssi and frequency

6 Start to parse RDS

7 Turn off FMPower

8 Turn off RDS FM power

9 Switch audio path

10 RSSI sweep

11 Turn off FMPower

I found these thanks to the O.P so credit to him, what a good hidden feature.

After "su" command I can't find the "fm_hcitool" command on my Dell Streak with 1.6 OS.

Where is it ?

open terminal emulator

type "su" enter

type "fm_hcitool 1" enter

then type "fm_hcitool 3 937" enter (for FM 93.7)

[Guest steflucrene]

Wow Geat...It works very well !!!!

Thank you

[Guest maskaler]

This is brilliant! Nice one!

I've downloaded the Android Scripting Environment, which you can get here:

And have created a couple of scripts. One called radio4.sh, the content of which is

clear

su -c "fm_hcitool 1"

su -c "fm_hcitool 3 945"

and one called closeRadio.sh :

su -c "fm_hcitool 11"

Hope these help you. If anyone has any better methods for doing this do post them!

Ant

Thanks, FM radio works perfect. Now all we need a GUI for it :lol:

@maskaler - Using a script seems good at the moment. Thank you!

i don understand how i can use this?

[Guest mrmrmrmr]

open terminal emulator

type "su" enter

type "fm_hcitool 1" enter

then type "fm_hcitool 3 937" enter (for FM 93.7)

# fm_hcitool 1

fm_hcitool: not found

So, I don't have it.

should I enable something before doing that ?

btw, I have 1.6 OS. Anyone with 1.6 OS and whohas fm_hcitool command ?

[Guest XsCode]

In the process of creating a GUI, it won't be pretty to start with but it should be functional. I'm using it as a project to learn Android dev. So far I have the radio turning on and off... stay tuned :lol:

[Guest Amdathlonuk]

stay tuned :lol:

I will, as soon as you finish your first .apk!

The first line of this thread states that it does not work with 1.6...

[Guest haynesteve]

Fabulous - shouldn't be long before you clever techie guys bring out a GUI.

[Guest mrmrmrmr]

ok;now I upgraded to 2.1 and it works :lol:

is there any chance to develop a gui with RDS ?

[Guest clickspace]

Thanks, listening now!

Cant wait for the UI. Using Ant's suggestion for the time being, thank you too.

Not listened to radio for AGES.

[Guest gillebob]

Really excited you're working on an FM fix, i swore i'd never buy another phone without a radio, just couldn't resist this monster.

BTW i've tried entering the code "fm_hcitool 1" and i get "device open failed: Operation not permitted" , I'm rooted and have other root apps working, any idea's?

My bad, didn't enter the "su" first...... :lol:

[Guest XsCode]

Ok, it's quick an dirty, but here it is....

you need to use the up and down arrows to select the frequency at the moment, but it should remember the frequency between loads. Will try to implement more stuff as I learn more java.

[Guest popetodd]

Sweet! You open sourcing this or going for the Market with it?

If it's OS can I have a look at the source?

[Guest XsCode]

not using market till i get a LOT better... I can make it opensource even tho it's just creating a process then issuing "su" then the commands as needed..... nothing special. Like I said previously, it's a project to learn Android programming...
