Option non blocking registration at gateway

Heizelmann

I am now ready with my node and I need the non-blocking feature urgently. Is there an estimation when this feature will be come or can anyone provide a workaround?

hek

If you use the development branch and want to prohibit the registration wait. Add

#define MY_TRANSPORT_WAIT_READY_MS 1

@tekka, correct me if I'm wrong please ;)

tekka

@hek correct :+1:
@Heizelmann Would be good to get some feedback on this feature, please let us know how it works in your hands.

Heizelmann

Here my report after a quick test.

To say it short: Generally I am happy with it, it works very well. Only one small problem.

In detail:
When connection is initially off, the sketch entered after the defined wait the loop.

before()
5 TSM:INIT
7 TSF:WUR:MS=1000
13 !TSM:INIT:TSP FAIL
15 TSM:FAIL:CNT=1
17 TSM:FAIL:PDT
1008 MCO:BGN:STP
Setup()
1510 MCO:BGN:INIT OK,TSP=0

If the sketch tries to send within the loop a message is logged.

145312 !MCO:SND:NODE NOT REG

If connection comes back the sketch connects to the gateway on the fly within the defined wait time.

Only problem is that you get high logging traffic in the case when you are in loop and network connection gets lost again as long as the connection is lost.

@Heizelmann Thanks for your testing. I couldn't reproduce this behavior, can you post your sketch for further analysis?

Heizelmann

@tekka May be it is the kind of my testing. For getting quick results I simply plug and un-plug the radio module (NRF24L01+) from the socket in my sensor node. I know, this is not a real use case but it was easy and I didn't thought there is adifference in behaviour. How do you you switch off and on the network connection in your test?

tekka

@Heizelmann yes, unplugging the radio results in what you observed. Simply unplug the GW (and repeaters)...

Heizelmann

@tekka OK unplugging the GW leads to a different behaviour.
First the node didn't detect the failure as long it is not trying to send.
When it tries to send it fails

131268 !TSF:MSG:SEND,42-42-0-0,s=1,c=1,t=16,pt=0,l=1,sg=0,ft=0,st=NACK:1

and after some more failure this

When gateway comes back a proper reinitialization takes place:

622660 TSM:UPL:OK
622662 TSM:READY:ID=42,PAR=0,DIS=1

From now the sensor can send again without errors. :smiley:
So far my tests.
Except the case where the radio of the sensor went off and causes a lot of logging all test cases where satisfactorily.
I think this is really an edge case and not so serious.
From this point of view I would welcome that this beta development version will be published.

I tested my node with the "#define MY_TRANSPORT_WAIT_READY_MS 1" feature.
It seems to work fine!
Tnx for the work.

Heizelmann

I detected another problem. From debug log it looks like the loop() function starts before initialization is finished. This can cause problems when trying to send data in loop() very early.

@Heizelmann I'm not sure I understood your concern.

Initialization is finished here, right before the main loop is entered:

1512 MCO:BGN:INIT OK,TSP=0

Since your timeout is set to 1sec (which obviously is too short to fully establish the transport link) the node will enter the main loop() after the timeout. However, since the link is not established, only init messages are sent at that point (i.e. library init, signing preferences, presentation). Sensor data will not be sent until the node is registered.
