Wrong generation of node IDs during presentation #152

Open subakun opened 6 years ago

subakun commented 6 years ago

[branch master - version 0.14.0 - Using serial gateway - NO asyncio] When presenting a new sensor node it sometimes happens (about 50% of times) that an extra Node ID is generated with all keys set to null. For example if I present a new node to an empty Json file the node ID=1 is generated with all null values and then the Node ID=2 is generated and the sensor is presented correctly. Sometimes things get even worse and a few empty nodes (3 or 4) are generated before the Node gets presented correctly. Please see attached .json file after the presentation of three sensor nodes. mysensors.json.txt

Can you also add a debug log of the node - gateway conversation that generates the problematic persistence file?

Hi Martin, many thanks for your reply ! I will try to re-produce the problem and log the gateway debug output. I wont be able to work on it until tonight.

Martin, for the moment I cant reproduce the problem but I have noticed that sometimes the presentation of a child sensor is delayed with respect the generation of a new node ID. it could be because a presentation message get corrupted by another node sending its "set" messages . . . ?. Let's leave the issue open for now, I want to see if the problem shows up again....

Did it show up again?
