Getting started
-
Install the server
The server is a single program for a computer. When started, it
shows an address such as
192.168.1.50:7700— this is the address of your radio. - Add people In the server management panel, section “Members”. Each member is given a login and a password. There is no self-registration.
- Connect phones On the same Wi-Fi network, the app finds the server automatically. If the server is not found, choose “Enter manually” and specify the server address.
If something does not work
The phone does not find the server
Most often the cause is the network settings. Check in order:
- The phone and the server are on the same Wi-Fi network. A guest network and a work network are different networks, even if the router is the same.
- Guest networks often have client isolation enabled: devices have internet access but cannot see each other. Such a network is not suitable for the radio.
- It is recommended to turn off mobile data on the phone: it may intercept traffic.
- If this does not help, enter the address manually. Automatic search is not the only way to connect.
Unable to sign in
The login and password are issued and changed by the administrator of your server. We cannot recover a password or create an account: we have no access to your server.
Other members cannot be heard
- Check the volume and the “Do Not Disturb” mode.
- If a headset is connected, the sound goes to it.
- In the radio channel, the top shows who is speaking. If it is empty, nobody has gone on air.
Other members cannot hear you
The app requests microphone access the first time you press the push-to-talk button. If access was denied, enable it again: Android Settings → Apps → Racia → Permissions → Microphone.
Reception stops when the screen is off
This should not happen: while the radio is receiving, the “Receiving” icon is shown in the notification shade, and the connection is kept with the screen off.
If reception is still interrupted, the cause is usually battery saving. Xiaomi, Huawei, Oppo, vivo and Samsung phones close background apps more strictly than Android itself. Find Racia in the battery settings and remove the restriction. The option is called “Don’t restrict”, “Autostart” or “Unrestricted”, depending on the phone.
No Wi-Fi
The app has a “Server on the phone” mode: one phone works as the server for all members on the same network. The fully standalone option, in which the phone creates a network by itself without a router, is under development and has not yet been tested on real devices; it should not be relied upon.
What we cannot do
This is a feature of how the product is built: the server through which your communication runs belongs to you, not to us.
- We do not see your messages and do not hear the air.
- We do not recover passwords and do not create accounts.
- We cannot retrieve messages from your server if it has failed or is switched off.
We have our own server: it serves this site and the installers and is not connected to your messages and air. For details, see the privacy policy.
Contacting support
If the problem is in the program itself (an error, a crash, behavior that does not match the description), write to hello@core-stack.ru.
To help us resolve it faster, include in the email:
- The phone model and the Android version.
- The app version — it is at the bottom of the “Settings” screen.
- What you did and what result you expected.
