fake packets?

[TropicalSeedlings]

My gateway is in remote area surrounded by hills - I do not think there are any nodes around.

Is it possible to recieve fake packets? Last night I got 3 packets, one with CRC error so I assume the other ones have correct CRC.. but they do not appear in console - Received Messages 0.
(I can't test it with my own node yet - waiting for stuff)

In issue #13 opened on Apr 8 iotlearner0level wrote about the frequency - I have chan:0 - 868.10 and plan for gateway in console set to Europe.

Log shows a little bit different (25Hz) frequency (868.099975) - is that OK for server to accept packet?
(iotlearner0level's log shows over 5kHz difference from 433.18MHz)
I can see my gateway online so there is no port/Internet related issue.

Hi,

I hope that the RFM95 together with the CRC error checking will only pass message that are OK. If there are CRC problems, please discard that message.
Unfortunately I cannot check whether this is because and unknown node was received, or an error was passed as successful or etc etc.. I hope that the node ID that is passed tells you more about the node.

I have 10 single channels as test machines working and I setup the "TRUSTED" nodes feature in gateway.h so I can check whether some nodes are not mine. I do not see many (there are a few in Apeldoorn but not many).

Please use the latest software version 5.1.1 that I uploaded today, it enables downloading of logfiles in the browser, Please check again.

regards,

Maarten

I am closing this issue, I do not find such fake nodes myself. Please re-open if you have more information.
