Abort from device: 4 about bacnet HOT 7 CLOSED

Hi @ReiminkB, can you post the part where you call ReadPropertyRequest and tell me what kind of object and property you want to read from?

Closing due to lack of feedback

@ReiminkB thanks for the feedback. Could you please try the latest beta (1.0.19) and see if you get a more human friendly message? Abort code 4 means that segmentations is not supported. Your device has too many objects and you can't read them due to lack of segmentation support (read more about it here). You need to read one object at a time using indexes.

Try this (I just typed it here so no guarantee it works but you will get the idea):

var propertyId = BacnetPropertyIds.PROP_OBJECT_LIST;
client.ReadPropertyRequest(device.Ip, objectId, propertyId, out value_list, arrayIndex: 0);
var objectCount = value_list.First().As<int>();

for (uint i = 1; i <= objectCount; i++)
{
    client.ReadPropertyRequest(device.Ip, objectId, propertyId, out value_list, arrayIndex: i);
    object_list.AddLast(value_list.First().As<BacnetObjectId>());
}

@gralin thanks for the answer. I replace 1.0.13 for 1.0.19-beta and got indeed the message: "Abort from device, reason: SEGMENTATION_NOT_SUPPORTED"

Thanks for the useful information from that link.

I adjusted my code by reading the properties one by one, as you suggested, when trying to read the complete list fails.

I tested the code and now it works for that device as well.

Thanks!

@ReiminkB I'm glad it works for you! If you find this lib useful please give it a star 😇 I'm planning a rewrite of the API so it's more user friendly, so stick around for v2 in near future.

So, is there no way to read more than one object at a time, let's say, read in chunks of 10 objects?
