Does not appear to work on RPI3

PedroC1999 commented 7 years ago

Hello!

Just saw your write up on your blog and I would like to try this myself, I ran the install instructions as per your Github and the RPI appears to be broadcasting sits bluetooth and I can succesfully connect. However the Pi does not appear to be transmitting and I have no idea how to fetch a log or debug this. Could you help guide me?

morrolinux commented 7 years ago

Hello, which frequency have you put in pirateradio.config? default freq. is 88.8 if you don't set one. Also, Have you tried attaching a usb key with at least one mp3 in it? I haven't tested it yet, but i think the raspberry could loop (restarting) forever if no mp3 to play is found, making it impossible to play even bluetooth. Thanks for your feedback, please let me know if it helps :)

PedroC1999 commented 7 years ago

I've set it at 108.0 to make it easier to find in my radio (no digital tuner)

I haven't tried it, is it a case of place the MP3 in the root of the USB?

Also, is there a way to even check its running? I just reboot my Pi and its "working" or do I need to launch any script?

morrolinux commented 7 years ago

You can put a mp3 file in any directory of your USB key, even the root or a sub-folder. Of course you can start it, stop it, and even check if it's running by using the standard systemd commands since it's a service: (which runs automatically at boot completed)

sudo systemctl status mpradio sudo systemctl start mpradio sudo systemctl stop mpradio Etc... I'm going to add some more instructions in the readme of the project so that everyone can read them directly in the home page

PedroC1999 commented 7 years ago

Okay,

I get home relatively soon and will be able to test this for you. I'll happily work with you in testing if you require anything

Thanks again, Pedro

Below is the output of the status command, does not appear to be transmitting the MP3 either. Clean install on Rasbian

Thanks for the trial. Have you already tried after booting with a usb key loaded with one mp3 file? PS: i see there's a specific error: find: ‘/pirateradio’: No such file or directory try to fix it with $ sudo mkdir /pirateradio before you plug in the usb key and reboot. Thanks

heres the output now, one mp3 onboard

morrolinux commented 7 years ago

seems like it's running.. do you hear anything?

PedroC1999 commented 7 years ago

I will have to set it up in my car, I don't think this radio is picking it up. I am using about 25cm of single core unshielded bare wire and I am within 50cm of the radio.

Does that sound alright?

Yea it should be okay! i wonder why you weren't able to pick it up... well let me know how it goes when you get in your car (y)

PedroC1999 commented 7 years ago

Nope! Couldn't get it to work. 1 file on the USB indicating it to broadcast on 108.0, and another being the MP3 file.

Also tried connecting to blue tooth and still nothing would play

PedroC1999 commented 7 years ago

Would it be possible to have a recent DD image send to me or uploaded?

morrolinux commented 7 years ago

Well, that wouldn't work out of the box, since PiFmRDS needs to be recompiled upon hardware change... BUT.. if you would help me debugging this, i have few extra questions to ask you and everyone else would benefit from it too...

can you please type $ ps aux | grep -i pifm and paste here the output? there should be a command line with all parameters used to launch the FM streamer application, so we can check if it's running on the right settings

PedroC1999 commented 7 years ago

cant hear anything still, do you require anything else?

morrolinux commented 7 years ago

Maybe I forgot to mention I just updated the repository, have you installed the latest version already? Also, please try to plug a USB key with one mp3 on it (no strange characters in the name) and no configuration file. Reboot, Then you should really try to tune 88.8 on your radio and see what happens.

PedroC1999 commented 7 years ago

I will update again, I had done it once but shall do it again just incase

PedroC1999 commented 7 years ago

i also renamed the mp3 to song.mp3

morrolinux commented 7 years ago

Damn, I'm not sure since when crudini is case sensitive... anyway I just noticed i was not able to set a custom frequency because of it: As I'm writing, I just updated the settingsprovider.cc to match [PIRATERADIO] instead of [pirateradio] (uppercase instead of lowercase) which is more ini-compliant. I'm sorry for those continuous updates, but I think we're going to make it.

PedroC1999 commented 7 years ago

Dont be sorry, just hope to get this working!

PiFM has worked on my Pi before, and I have reset it multiple times since.

Again, I did not hear anything. Does PiFM produce any logs etc?

morrolinux commented 7 years ago

This could be not just about PiFm but more likely mpradio (my implementation) which has few weaknesses. Anyway, you can stop mpradio service and launch /home/pi/mpradio manually from shell. You should then see something useful on the screen

morrolinux commented 7 years ago

anyway you should fetch and update to the latest commit: i personally tested and seems to be working alright with a usb key:

song.mp3
pirateradio.config: [PIRATERADIO] frequency=107.0

and even without the config file, it's correctly defaulting to 88.8.. i also solved a process stall that used to keep the cpu 100% busy restarting forever the process, when no mp3 was provided. That said, it's all to be tested now :)

PedroC1999 commented 7 years ago

I have removed the config file anyway to remove more variables. Trying now

PedroC1999 commented 7 years ago

Okay - even without a config file, it appears to be running at 107 (or atleast thats the shell output)

secondly, with bluetooth connected or not, i still get a "no bluetooth device, playing mp3" shell output.

and still no transmission

PedroC1999 commented 7 years ago

just to add, I am using the RPi 3's built in bluetooth and connecting/pairing works fine

morrolinux commented 7 years ago

If you are picking up 107.0 , that means your USB key is not mounted, and mpradio is picking up the default configuration file located at /pirateradio/pirateradio.config (which is masked with the real usb key root, when a usb key is plugged) therefore, there is no mp3 file to play and the program quits without playing anything.

As for the bluetooth message: if you launch ./mpradio without parameters, it will always give you that message. there is a specific udev script in charge of launching mpradio with the bluez_device.YOUR_BT_ADDRESS.bt_audio (or something) automatically when you connect via bluetooth... but we will take care about it later on..

for the moment, you should try to understand why the usb key is not mounted at all, and remember: 1) USB key should be in FAT32 filesystem 2) USB key should have just one partition 3) msdos partition schema, NOT GPT

$ mount | grep pirateradio should give you something like /dev/sda1 /pirateradio/ if the key is mounted, or nothing if is not.

also try $ ls /pirateradio/ to see if your mp3 is there (which is not, ATM)

PedroC1999 commented 7 years ago

I have a USB2.0 device plugged into the Pi3, its formatted as "DATABAR" and its accessible from the Pi's file explorer, where the song is visible.

PedroC1999 commented 7 years ago

The MP3 is not listed when I run that command, Pirateradio.config is (this is not on my USB drive)

morrolinux commented 7 years ago

1) I think the USB key is mounted in a different location than /pirateradio/ hence, you see pirateradio.conf and not your mp3 (which is not the content of your USB key) 2) you should really disable graphical sessions on your raspberry or at least kill them, as they can intercept new devices upon connection and cause the problem in point 1)

PedroC1999 commented 7 years ago

I am not great at Unix commands and do struggle slightly - sometimes I find it useful.

Would it be possible to run a command to mount it properly

morrolinux commented 7 years ago

You have to unmount it from graphical session first, and then run $ sudo mount -a to make it happen. That said, graphical session is nothing useful for what we're doing here, and can cause so much trouble.. consider disabling it before you put your Pi into your car, to avoid having to type those commands before driving ;)

PedroC1999 commented 7 years ago

Oh yes definitely haha,

I unmounted the volume in GUI and disconnected. Then I ran the mount command and the outputs were the same

morrolinux commented 7 years ago

Ok, let's try to start over: 1) disconnect your graphical session (disable it, even temporarily, would be optimal) 2) $ sudo umount /pirateradio (just to make sure) 3) ensure your usb is plugged and $ sudo mount /dev/sda1 /pirateradio 4) $ ls /pirateradio should list your mp3 on the on the USB key 5) $ sudo systemctl stop mpradio && sudo systemctl start mpradio 6) now you should start hearing something on 88.8 (if there's no config file)

Partition table entries are not in disk order. pi@raspberrypi:~ $ sudo mount /dev/sda /pirateradio pi@raspberrypi:~ $ ls /pirateradio pirateradio.config pi@raspberrypi:~ $ sudo ls /pirateradio pirateradio.config

Above is my disk info, as we see we have a 2gb USB device that is connected and supposedly mounted, but is not listed

You don't just mount /dev/sda which is the physical device. You must refer to the partition to be mounted, and I see you have 4: sda1 sda2 sda3 sda4 So you have to specify either /dev/sda1 or /dev/sda2 and so on... By default, mpradio would mount /dev/sda1 but maybe in your USB key that's not a fat32 partition. To make things easier I would suggest you to format your USB key on your computer making just one big FAT partition in which you place your mp3s
