The LinkADRReq payload enables unexpected uplink channels


#1

Hi, first thanks for the great software.

I’ve been using your server with some success but have run into issues with the ADR feature.

i’m trying to use ADR for node,so first, i’m enabled the ADR flags on node. second, i’m always configured the ADR interval, Installation margin (dB) option in [Advanced network settings], ADR interval value is 4, Installation margin is 5dB.

and now, the node can received the LinkADRReq mac command, but the payload was strange, the payload’s value such as following Hexadecimal data:[53ffff01], the command asking node enabled the 470.3MHz-471.7MHz channels to uplink, but i never enabled the channels in node, the node default’s uplink cahnnles list 475.1-476.5MHz.

so I can’t understand the ADR feature. Could you help me?


#3


node’s default enabled channels is
LoRaMacParamsDefaults.ChannelsMask [1] = 0x00ff;


#4

Your using the CN 470-510MHz Band? Please note that you can control the enabled channels using the --enable-uplink-channels. config flag.


#5

I am sorry for my late reply. Thanks for your reply, I trying to use the --enable-uplink-channels. config flag. But still does not work.

if we enabled --enable-uplink-channels config flag on loraserver,the ADR feature will can’t work, I don’t know why, maybe i can’t understand the enabled-uplink-channels flag means what.
–enable-uplink-channels value enable only a given sub-set of channels (e.g. ‘0-7,8-15’), in my opinion the given sub-set of channels will be used to ADR feature?

i don’t understand why the ADRRreq command’s payload enables upexpected uplink channels, Chmask always be set 0xffff, ChMaskCntl always be set 0, the Chmask and ChMaskCntl’s values will enabled the invalid uplink channels , but the gateway never listening these channels.

i think this is a problem on loraserver.


#6

What is the vendor and type of your device? And could you post a screenshot of the relevant raw frame-logs (please expand the fOpts key so we can see the content of the Mac-commands).


#7

OK, The gateway and node is our own designed. node’s source code based on the following linksLoRaMac-node, node run in classA.

And i’ll post later, thank you for your reply.


#8

i add the log’s printf in handleUplinkMACCommands function, and adr.HandleADR function, they will printf the uplink’s mac-commands and LinkADRReq mac-command.

and the log’s of loraserver

and the screenshot of loraserver are there.






#10

i have a another question, why node does not support adr feature when they run on classA and OTAA?


#11

I might not understand raw frame-logs what does means. i post som raw frame-logs of loraserver. maybe you want to this?


#12

What do you have in your LoRa Server --enable-uplink-channels / ENABLE_UPLINK_CHANNELS configuration? See also https://docs.loraserver.io/loraserver/install/config/

As you can see in the logs, LoRa Server is activating the following channels on purpose (either by misconfiguration or bug):

INFO[0102] link_adr request acknowledged dev_eui=9bf728017a881379 dr=5 enabled_channels=[0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95] nb_trans=3 tx_power_idx=5

#13

in my LoRa Server --enable-uplink-channels=“8-15,24-31”。


#14

this is my fault about the --enable-uplink-channels option doesn’t work.

I wrote the error format for --enable-uplink-channels [–enable-uplink-channels=8-15,24-31]

correct format must be wrote [–enable-uplink-channels=“8-15,24-31”]

Now this option can be used for ADR feature, But they still can’t change the node’s uplinkChannels. change channels [8-15] to channels [24-31], when the best gateway was be closed, the best gateway be configuration listening channels are [8-15].


#15

Example command: loraserver --enable-uplink-channels=0-7 should result in something like this in the logs:

INFO[0000] disabling all channels
INFO[0000] enabling channel block                        first_channel=0 last_channel=7

If not, then the config params are incorrect. When you re-activate your node (OTAA), you will see that LoRa Server will enable these channels on your node and disable all other channels. This is not just for ADR! Even for nodes with ADR turned off, LoRa Server will re-configure the channels.


#16

yes, you’re right. --enable-uplink-channels option can change node’s channels. thanks your reply,:kissing:, i fix my problem.


#17

But i have a another question, why node does not support adr feature when they run on classA and OTAA?


#18

ADR should work for ClassA nodes activated with OTAA. But in case of questions, please create a separate topic :slight_smile:


#19

emm, okay, thanks. :grin:


#20

Hi, I seem to be having a similar issue. I’m using the US_902_928 band with ADR enabled on the network server and on my end nodes (mDot). My gateway and end nodes are configured for sub-band 1. However, after the LinkADRReq is received, the end node begins using FSB1 and FSB2 (16 channels) which causes 50% of the uplinks to fail.

If I set ENABLE_UPLINK_CHANNELS=0-7 then ADR attempts to disable all channels (all chMask values are false). The mDot rejects this with an error “[WARNING] Rejecting ADR command to disable all channels”.

So it seems the channel mask is either all or nothing. How can I use ADR with only 8 uplink channels?

Thank you!


#21

I believe LoRa Server sends two maccommands. One to turn everything off, the other to turn on a selected set of channels. The device must handle this block of commands atomically (thus not turn everything off, then turn 0-7 on but every channel other than 0-7 off).
