set a time delay in java operation

[Anduril]

Hey there,

I have a node with multiple sensors and want to update them with a java script. I have signatures activated and us an RFM69 transmitter on my gateway.

1574774 TSF:MSG:READ,0-0-17,s=21,c=3,t=16,pt=0,l=0,sg=0:
1574793 TSF:MSG:SEND,17-17-0-0,s=255,c=3,t=17,pt=6,l=25,sg=0,ft=0,st=OK:<NONCE>
1574814 TSF:MSG:READ,0-0-17,s=21,c=1,t=24,pt=0,l=17,sg=1:10000000000000000

1577584 !TSF:MSG:SIGN FAIL

I think adding something like Thread.sleep(x) could solve the problem, as the signature transmission would have a little more time to avoid collission (but maybe I'm wrong). Sending them manually works absolutely fine.

mcApi.sensor().sendPayload(S1);
mcApi.sensor().sendPayload(S2);
mcApi.sensor().sendPayload(ID);
mcApi.sensor().sendPayload(Name1);
mcApi.sensor().sendPayload(Name2);

Is there any way to insert a kind of delay in a script?

@Anduril You can set Tx delay globally in your gateway settings

Still if you are looking sleep options,

var myImports = new JavaImporter(java.io, java.lang, java.util, java.text);

with(myImports) {
     Thread.sleep(500); // in milliseconds
}

@jkandasa thanks a lot (again) for that tip. My transmit delay was set, but maybe 100 ms were too low for signing to finish before the next message. Now I set it to 200 ms and it seems to work according to my first tests.
Another minor question: I added Names to my sensors (which were auto-detected during node presentation if that matters), but they get overwritten with for example 74522 TSF:MSG:READ,17-17-0,s=22,c=0,t=23,pt=0,l=0,sg=1: which seems to be the complete serial incoming message for that sensor. Is this know and is there a way to avoid this name-changing?

Yes, we have an option to lock the name. Add this property on your node.
"lockNode": true
