#Environment Variables
|
|
##Required global variables
|
|
* GW_ID required
|
|
* GW_KEY required
|
|
This gateway ID and gateway Key for TTN will be used to fetch the gateway's information form the TTN console. When SERVER_TTN is true, this will also be used to conenct and forward packets to TTN.
|
|
|
|
##Optional global variables
|
|
* GW_CONTACT_EMAIL optional - default an empty string
|
|
The gateway owner's contact information. Will be overridden by the value from the TTN console.
|
|
* GW_DESCRIPTION optional - default an empty string
|
|
A description of this gateway. Will be overridden by the value from the TTN console.
|
|
* GW_RESET_PIN - default 22
|
|
The physical pin number on the Raspberry Pi to which the concentrator's reset is connected. See the [README](README.md) file for a description and a list of common values.
|
|
* GW_GPS optional - default False
|
|
* If true, use the hardware GPS.
|
|
* If false,
|
|
use either fake gps if a location was configured in the TTN console,
|
|
otherwise try using fake gps with the reference location as set via environment variables,
|
|
otherwise don't send coordinates.
|
|
* GW_GPS_PORT optional - default /dev/ttyAMA0
|
|
The UART to which the hardware GPS is connected to.
|
|
* GW_REF_LATITUDE optional - default 0
|
|
The latitude to use for fake gps if the coordinates are not set in the TTN console.
|
|
* GW_REF_LONGITUDE optional - default 0
|
|
The longitude to use for fake gps if the coordinates are not set in the TTN console.
|
|
* GW_REF_ALTITUDE optional - default 0
|
|
The altitude to use for fake gps if the coordinates are not set in the TTN console.
|
|
* GW_FWD_CRC_ERR optional - default false
|
|
Forward packets with an invalid CRC.
|
|
* GW_FWD_CRC_VAL optional - default true.
|
|
Forward packets with a valid CRC.
|
|
* GW_ANTENNA_GAIN optional - default 0.
|
|
Set this to the dBd gain of your antenna. The dBd value is the dBi value minus 2.15dB, ie. dBd = dBi-2.15. This is used to reduce the TX power of the concentrator to stay within the legal limits.
|
|
|
|
##Server variables
|
|
All server variables are optional, but when a server is enabled, it is recommended to set all variables to configure it completely.
|
|
* SERVER_TTN optional - default true
|
|
Should the gateway connect to the TTN backend
|
|
|
|
* SERVER_1_ENABLED optional - default false
|
|
* SERVER_1_TYPE - default "semtech"
|
|
* SERVER_1_ADDRESS
|
|
* SERVER_1_PORTUP - only when using type semtech
|
|
* SERVER_1_PORTDOWN - only when using type semtech
|
|
* SERVER_1_GWID
|
|
* SERVER_1_GWKEY
|
|
* SERVER_1_DOWNLINK - default false
|
|
|
|
* SERVER_2_ENABLED optional - default false
|
|
* SERVER_2_TYPE - default "semtech"
|
|
* SERVER_2_ADDRESS
|
|
* SERVER_2_PORTUP - only when using type semtech
|
|
* SERVER_2_PORTDOWN - only when using type semtech
|
|
* SERVER_2_GWID
|
|
* SERVER_2_GWKEY
|
|
* SERVER_2_DOWNLINK - default false
|
|
|
|
* SERVER_3_ENABLED optional - default false
|
|
* SERVER_3_TYPE - default "semtech"
|
|
* SERVER_3_ADDRESS
|
|
* SERVER_3_PORTUP - only when using type semtech
|
|
* SERVER_3_PORTDOWN - only when using type semtech
|
|
* SERVER_3_GWID
|
|
* SERVER_3_GWKEY
|
|
* SERVER_3_DOWNLINK - default false
|
|
|
|
## Note about boolean values
|
|
|
|
Use `true` and `false` as lower case words to enable or disable features via environment variables. Any other format will not be interpreted correctly.

#Logal debugging
|
|
```
|
|
docker run --device /dev/ttyAMA0:/dev/ttyAMA0 --device /dev/mem:/dev/mem --privileged -e GW_TYPE="imst-ic880a-spi" -e GW_DESCRIPTION="test gateway" -e GW_CONTACT_EMAIL="" -e GW_ID="" -e GW_KEY="" newforwarder
|
|
|
|
|
|
```
|
|
Make a copy of `Dockerfile.template` to `Dockerfile`.
|
|
```
