-b --buffer <ms>

How many milliseconds are processed in advance (default = '50') A buffer below 10 ms requires low interval like 0.1 ms.

--rx-gain <dB>

Raise/lower receiver's RX level by given gain in dB. (Works with sound card only.)

--tx-gain <dB>

Raise/lower transmitters's RX level by given gain in dB. (Works with sound card only.)

-e --echo-test

Use echo test, to send back audio from mobile phone's microphone to the speaker. (German: 'Blasprobe').

-c --call-device hw:<card>,<device>[/hw:<card>.<rec-device>]

Sound card and device number for headset (default = '') You may specify a different recording device by using '/'.

--call-samplerate <rate>

Sample rate of sound device for headset (default = '48000')

--call-buffer <ms>

How many milliseconds are processed in advance (default = '50')

-x --osmocc-cross

Enable built-in call forwarding between mobiles. Be sure to have at least one control channel and two voice channels. Alternatively use one combined control+voice channel and one voice channels.

-o --osmocc-sock

Disable built-in call control and offer socket

--cc "<osmo-cc arg>" [--cc ...]

Pass arguments to Osmo-CC endpoint. Use '-cc help' for description.

--no-l16

Disable L16 (linear 16 bit) codec.

-t --tones 0 | 1

Connect call on setup/release to provide classic tones towards fixed network (default = '1')

-l --loopback <type>

Loopback test: 1 = internal | 2 = external | 3 = echo

-r --realtime <prio>

Set prio: 0 to disable, 99 for maximum (default = 0)

--fast-math

Use fast math approximation for slow CPU / ARM based systems.

--write-rx-wave <file>

Write received audio to given wave file.

--write-tx-wave <file>

Write transmitted audio to given wave file.

--read-rx-wave <file>

Replace received audio by given wave file.

--read-tx-wave <file>

Replace transmitted audio by given wave file.

--limesdr

Auto-select several required options for LimeSDR

--limesdr-mini

Auto-select several required options for LimeSDR Mini

SDR options:

--sdr-soapy

Force SoapySDR driver

--sdr-channel <channel #>

Give channel number for multi channel SDR device (default = 0)

--sdr-device-args <args>

--sdr-stream-args <args>

--sdr-tune-args <args>

Optional SDR device arguments, separated by comma e.g. --sdr-device-args <key>=<value>[,<key>=<value>[,...]]

--sdr-samplerate <samplerate>

Sample rate to use with SDR. By default it equals the regular sample rate.

--sdr-lo-offset <Hz>

Give frequency offset in Hz to move the local oscillator away from the target frequency. (default = -1000000)

--sdr-bandwidth <bandwidth>

Give IF filter bandwidth to use. If not, sample rate is used.

--sdr-rx-antenna <name>

SDR device's RX antenna name, use 'list' to get a list

--sdr-tx-antenna <name>

SDR device's TX antenna name, use 'list' to get a list

--sdr-clock-source <name>

SDR device's clock sourc name, use 'list' to get a list

--sdr-rx-gain <gain>

SDR device's RX gain in dB (default = 0.0)

--sdr-tx-gain <gain>

SDR device's TX gain in dB (default = 0.0)

--write-iq-rx-wave <file>

Write received IQ data to given wave file.

--write-iq-tx-wave <file>

--read-iq-rx-wave <file>

Replace received IQ data by given wave file.

--read-iq-tx-wave <file>

Replace transmitted IQ data by given wave file.

--sdr-swap-links

Swap RX and TX frequencies for loopback tests over the air.

--sdr-timestamps 1 | 0

Use TX timestamps on UHD device. (default = 1)

Network specific options:

-O --operator <number>

Give number to dial when mobile station initiated a call. A-Netz does not support automatic dialing, so operator assistance is required. By default, the operator '010' is dialed.

-G --geo <lat>,<lon>

Give your coordinates of your location, to find closest base station. (e.g. '--geo 51.186959,7.080194') Or use '--geo list' to get a list of all base station locations.

-V --page-gain <dB>

Raise the gain of paging tones to compensate loss due to pre-emphasis of the transmitter. (If you can't disable it.)

-P --page-sequence 0 | <ms>

Cycle paging tones, rather than sending simultaniously. Try 100. (default = '0')

-S --squelch <dB> | auto

Use given RF level to detect loss of signal. When the signal gets lost and stays below this level, the connection is released. Use 'auto' to do automatic noise floor calibration to detect loss. Only works with SDR! (disabled by default)

station_id: Give 5 or 7 digits of station ID,

so you don't need to enter it for every start of this application. Give 5 digits for number without channel prefix. Give 7 digits for number with channel prefix.

Press digits '0'..'9' and then 'd' key to dial towards mobile station. Press 'h' key to hangup. Press 'w' key to toggle display of RX wave form. Press 'c' key to toggle display of channel status. Press 'm' key to toggle display of measurement value. Press 'q' key to toggle display of RX I/Q vector. Press 's' key to toggle display of RX spectrum. Press 'b' key to remove DC level.
