Impinj Reader - connection already exists

[stuart lynne]

Has anyone looked at hacking a simple script to reboot an Impinj Reader when it gets into the "connection already exists" state?

Was thinking a simple shell script using curl should be able to log in and select the reboot button in the configuration screen.

Assuming we have that, then CrossMgrImpinj and RaceDB could incorporate the same to convince the reader that we really do want to connect without having to power cycle it manually.

Should be as simple as sending the "Reboot" command through RShell.

Didn't think of rshell (have not looked at that in donkey's years...)

This works for R1000 (with appropriate substitutions for login:password and IP address of course):

curl -u root:impinj -d "rebootsubmit=submitted" -X POST "http://10.16.29.136/cgi-bin/body_config.xsl?menu=config&rebootsubmit=submitted"

Was looking for this issue regarding my R220... I am unable to connect to my reader reader without restarting it after every reset of CrossMgrImpinj.. What I get is:

Get response fails: LLRP socket connection broken

Send Command Error=cannot unpack non-iterable bool object

Reader Initialization Failed.

Disconnecting Reader.

Attempting Reconnect in 2 seconds...

Do you think this is normal? With my Motorola FX9500, I have never run in to this kind of issue, without counting the occasional bugging out of CrossMgrImpinj, which requires restarting the program to be able to reconnect to the reader. 

Maybe a restart button for these reader models could be implemented in CrossMgrImpinj?

For my R220 on Win7 & using MSYS2 i figured out a command like this

plink -batch root@speedwayr-xx-xx-xx -pw impinj reboot

On Linux/WSL something like this can probably be used (remember to first make normal ssh connection to get the RSA key):

sshpass -p impinj ssh root@speedwayr-xx-xx-xx reboot

Check to see if the reader also has the impinge connect softwares running on it, that will use up the llrp socket

I was thinking about that too, but all I know is that the Connect software should be reachable at speedwayr-xx-xx-xx:8080, and I get nothing there. (port scan says only ports 80 & 22 are open too..) The reader is still connecting to 127.0.0.1 after a reboot, and not letting me connect with CrossMgrImpinj at all if I don't already have it running and trying to connect. hmm...

look at the webpage for the impinge reader it will show if llrp is already active or not before you try and connect with cross manager impinj

It says:

LLRP Status Connected: 127.0.0.1

RFID Status Active

I can only connect CrossMgrImpinj if I have it running when restarting the reader. Maybe there is some other software than Speedway Connect running on the reader? I'll check somethin via the SSH.

I can find at least this:

 show rfid llrp > summary

Status='0,Success'

LLRPPeerIPAddress='127.0.0.1'

LLRPPeerPort='50109'

LLRPPeerTransport='TCP'

LLRPConnType='LLRP (client-initiated)'

LLRPConnTime='Dec 14, 2019 04:53:51.918'

LLRPROSpecCount='1'

LLRPROSpec101='Inactive'

LLRPAccessSpecCount='0'

 show image > summary

PrimaryImageState='Active'

PrimaryImageSystemVersion='6.2.1.240'

PrimaryImageConfigVersion='255.255.255.255'

PrimaryImageCustomAppVersion='9.0.0.2'

SecondaryImageType='10'

SecondaryImageState='Active'

SecondaryImageSystemVersion='5.4.0.240'

SecondaryImageConfigVersion='255.255.255.255'

SecondaryImageCustomAppVersion='9.0.0.2'

According to the Impinj RShell Reference Manual and "CustomAppVersion", it definitely seems that there is some other application on the reader. I'll try to see what it is.

[Jonathan Rosen]

There is definitely a custom app installed and running in the cap partition, that app is grabbing the llrp session and preventing cross manager impinj from working. There is a command to wipe the cap partition.
