Error in FindControllersAsync

[scervellera]

Hello Jeff, I have upgraded my version from 1.5.10 to 1.6.1.

I have very often an error in XBeeController.FindControllersAsync

{System.IO.InvalidDataException: Found invalid data while decoding. at XBee.AtCommandWriter.<WriteAsync>d__3.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Core.XBeeControllerBase.<SetApiModeAsync>d__85.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Core.XBeeControllerBase.<InitializeAsync>d__84.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Core.XBeeControllerBase.<ExecuteAsync>d__83.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Core.XBeeControllerBase.<ExecuteQueryAsync>d__761.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Core.XBeeControllerBase.d80`1.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Core.XBeeControllerBase.d73.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Universal.XBeeController.d3.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at XBee.Universal.XBeeController.d1.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult() at IT.ITSellingSolution.OmniGreenMaster.XbeeHubNs.XBeeHub.d__89.MoveNext()}

I don't have this kind of error in 1.5.10 and I don't have made any changes to code.

Hm, that's a result of the API mode auto-configure from 1.6 not working. Can you please try 1.6.2-beta and post the exception if it happens again? I've added more debug info to the exception message. Thanks.

Hello, i was having the same problem with 1.6.1, tried 1.6.2-beta, and here it is the new error.

Hello, i forgot to specify some informations: -i'm working on a raspberry in UWP -the xbee connected to the raspberry is the coordinator

Anyway, i downloaded the sources so i can make more tests.

The problem is in SetApiModeAsync when you try to send : await writer.WriteAsync("+++").ConfigureAwait(false);

The response is AckResponse, only if xbee network is not established. In other case (a standard for our application) we don't have a AckResponse, but the 3 bytes that i always find in the response are : 126,0,35

[jefffhaynes]

Interesting. I’m not sure what would cause that. Let me spend more time on it.

If you get a chance can you try issuing “+++” from a serial terminal or X-CTU and see what you get?

Thanks

ok, tried from Tera-Term sotware. when i send +++, i always have OK as response. but when i receive a message from another xbee, the OK response is at the end of the message (see screenshot).

I think that is necessary to clean the already receveid messages on the serialdevice, or wait for any Ok response bytes in the stream.

[jefffhaynes]

Ah, of course. Ok, thank you.

Can you please try 1.6.2-beta3 and see if it works better for you? Thanks

[ilcearini]

it works. I tryed to start the app several times, and i've never had the error.

Thanks you!!

[jefffhaynes]

Great, glad to hear it
