I can't see the brd field in the https://github.com/Lora-net/packet_forwarder/blob/experimental/PROTOCOL.TXT i will check with my packet forwarder provider if the value is correct and if values upper than 255 will be provided in the future.
The brd
is used by for example the iBTS gateway as it can contain up to 4 boards (each serving 16 channels). I could change from uint8
to a type able to store larger numbers, but it would be good to validate what brd: 261
means :-)
So,
on the https://github.com/brocaar/loraserver/blob/master/api/gw/gw.pb.go#L558 it's defined as an uint32.
From kerlink collegues :
On PROTOCOL.TXT and the protocol GWMP 1.5, Semtech has defined a brd field as : brd | number | Concentrator board used for RX (unsigned integer)
There is no size defined. the lns must transmit the value without change (blackbox for the LNS).
Kerlink use this field to transmit more information on it :
Bits | Name | Description |
---|---|---|
31-24 | Unused | |
23-20 | Zone | Antenna zone (refers to the system) |
19-16 | Antenna | Antenna identifier (refers to the system) |
15-12 | Board | Board identifier (refers to the system) |
11-8 | Transceiver | Transceiver identifier (refers to the board) |
7-4 | Demodulator | Demodulator identifier (refers to the board) |
3-0 | Channel | Channel identifier (refers to the demodulator) |
is it ok for you to transform the field to uint32 (I can prepare a PR) ?
Yes, please do :-)
Is this a bug or a feature request?
maybe a bug
What did you expect?
On my lora-gateway-bridge the packets are not transmitted to the loraserver due to a json parsing error :
on the JSON, the brd value is 261 (incorrect uint8 value)
Have you an idea about the root cause error ?
