Usb stick and controlls

[vvervolv]

Good afternoon! Thank you so much for Mpradio-py! But I have some problems.

1. I use Raspberry PI 3 B+. After installation, I succesful connect to the device via bluetooth, but unfortunately the music was not broadcast on FM. But, if I connect a USB stick with a configuration file, everything is OK (Except for the companion application, it does not allow doing anything). I want to use my PI in the car, so I want to minimize the size, so how can i make it works without usb stick?
2. My push-button control does not work (GPIO-connected on pin 5 [BCM 3]).

I guess that GPIO and application problems are same

Please, tell me where to look for an error

P.S. Sorry for my English

Hi, Can you elaborate on 1.) describing what happens when you try to connect via Bluetooth for audio playback? Right now during mpradio-py installation a line is written in /etc/fstab for automatically mounting a device called /dev/sda1 (which would be your USB stick if you plug it in). You could partition your SD CARD making a new FAT32 partition and storing everything there, but to make it work in this configuration, you should change /dev/sda1 with the partition name you just created. you can find it using sudo fdisk -l looking for the last partition.

as for 2.) can you test by simply short-circuiting with GND? I'm gonna guess it's an hardware problem unless an exception is raised in the logs of journalctl -f mpradio

Hello! Thank you for answer! When i try to connect my phone to Pi (without usb stick), it connects succesful (bluetoothctl says that). But when i try to play music, only silence (not noise) is heard from the radio (and MPRadio remote app does not start, like PI is disconnect). sudo systemctl status mpradio says :

pi@raspberrypi:~ $ sudo systemctl status mpradio ● mpradio.service - Morrolinux Pirate Radio Loaded: loaded (/etc/systemd/system/mpradio.service; enabled; vendor preset: enabled) Active: active (running) since Tue 2019-09-24 09:33:13 MSK; 5min ago Main PID: 459 (python3) Tasks: 11 (limit: 2200) Memory: 57.7M CGroup: /system.slice/mpradio.service ├─459 python3 /home/pi/mpradio.py ├─540 sox -t raw -G -b 16 -e signed -c 2 -r 44100 - -t wav - compand 0.3,1 6:-70,-60,-20 -5 -90 0.2 treble -6 ├─544 sudo pi_fm_adv --freq 88.0 --ctl /tmp/rds_ctl --audio - └─551 pi_fm_adv --freq 88.0 --ctl /tmp/rds_ctl --audio - Sep 24 09:33:13 raspberrypi systemd[1]: Started Morrolinux Pirate Radio.

But when i plug in usb stick, integer expression expected dissapeared, and it starts play music from usb and from bluetooth (App starts, but buttons (like halt or reboot) not working).

I will try to make FAT32 partition tommorow, i forgot my cardreader at home :)

For 2.) I try to short-circuiting with GND, but nothing happens. When i try to journalctl -f mpradio it says

Failed to add match 'mpradio': Invalid argument

But it works on previous version of MPRadio (the old implementation) Is it possible that the problem is caused by the NOOBS->raspbian lite distributive?

Thank you!

That error is not relevant to mpradio

and it starts play music from usb and from bluetooth

By that you mean you're then able to play bluetooth audio from your phone as well?

(App starts, but buttons (like halt or reboot) not working).

The App is being adapted from the legacy mpradio version server backend. There are some minor differences and I haven't completed it yet. What should work:

1. Tracks listing and on demand track playback
2. Skip button
3. Maybe some others but I'm not sure

I try to short-circuiting with GND, but nothing happens. When i try to journalctl -f mpradio it says

Oh yeah sorry about that it's journalctl -fu mpradio. If you don't specify u you're not telling journalctl which unit to look at.

Is it possible that the problem is caused by the NOOBS->raspbian lite distributive?

Speaking of Debian... which version are you running on? 9 or 10?
