This message usually represents wrong join parameters, such as Appkey mismatch. And the sensors may carry a random Appkey at the factory, resulting in a mismatch with the default Appkey. So please share the SN of these two devices to me to help me check if the Appkey of these two devices is a random number.
This ist not suitable for our production and logistics process. I need to know the AppKey and AppEUI for my devices as part of the socumentation sjhipped wioth the devices or in an automatic way. It is not practible to send you an Email every time we ship 1, 10 oder 100 devices to our customers.
Best Regards
Peter
Typically, If the device is shipped with a random Appkey, we will send the distributor or reseller a file that corresponds to the device's EUI and Appkey. So if the random appkey situation occurs subsequently, please check with your reseller or distributor.
For this issue at the moment, we would recommend that you could send me the SN of these two devices first, and I can check the corresponding Appkey for you to see if it is correct.

I try to register a series of five AT101 868 on The Thisngs Network but got on two different devices the Messages "MIC Mismatch ..."
1) The device are new and out of the box
2) I never registered the devices before
3) I use the AppEUI 24E124C0002A0001 (Default from AT101 Manual)
4) I use the AppKEy 5572404C696E6B4C6F52613230313823 (Default from AT101 Manual)
5) I use DevEUI retrieved from Milesight Toolbox
What could be the problem? Please suggest possible solutions to this problem.
Thanks Peter
