Hello @all
I have a question about the channels in LoraServer Config:
Here is a example of the conifg:
**> # Enable only a given sub-set of channels**
**> #**
**> # Use this when ony a sub-set of the by default enabled channels are being**
**> # used. For example when only using the first 8 channels of the US band.**
**> # Note: when left blank, all channels will be enabled.**
**> # **
**> # Example:**
**> # enabled_uplink_channels=[0, 1, 2, 3, 4, 5, 6, 7]**
**> enabled_uplink_channels=[]**
**> **
**> # Extra channel configuration.**
**> #**
**> # Use this for LoRaWAN regions where it is possible to extend the by default**
**> # available channels with additional channels (e.g. the EU band).**
**> # The first 5 channels will be configured as part of the OTAA join-response**
**> # (using the CFList field).**
**> # The other channels (or channel / data-rate changes) will be (re)configured**
**> # using the NewChannelReq mac-command.**
**> #**
**> # Example:**
**> # [[network_server.network_settings.extra_channels]]**
**> # frequency=867100000**
**> # min_dr=0**
**> # max_dr=5**
**> **
**> # [[network_server.network_settings.extra_channels]]**
**> # frequency=867300000**
**> # min_dr=0**
**> # max_dr=5**
**> **
**> # [[network_server.network_settings.extra_channels]]**
**> # frequency=867500000**
**> # min_dr=0**
**> # max_dr=5**
**> **
**> # [[network_server.network_settings.extra_channels]]**
**> # frequency=867700000**
**> # min_dr=0**
**> # max_dr=5**
**> **
**> # [[network_server.network_settings.extra_channels]]**
**> # frequency=867900000**
**> # min_dr=0**
**> # max_dr=5**
- I’ am in the EU, so i use the EU-Frequencies.
- i have not enabled the extra bands in the config
- enabled_uplink_channels=[] means all Channels are activ (not only a some sub channels)
Now my Questions:
- As i do not have activated extra channels, why do i still recieve data on this frequencies according to lora-app-server “Live Lorawanf Frame”?
- what happens if i activate this extra channels?
- Would it be a valid configuration to activate the extra-channels and use the sub band 0,1,2 (which are the dafault channels i guess)?
Background of my question is the following:
we have a gateway and about 30 sensors. the sensors send data every 10 minutes. but we loose about 40% of all data packages. i dont know where we loose them. so if anyone can help me with this or has any idea, would be great.
thx, sil
to be complete, there is the config of the multitech packet frowarder.
