MIC Mismatch when trying to connect to TTN

For those who can’t push updates, an AppEUI of 0x1 is sufficient as long as the user doesn’t hit endian issues (and that’s what we normally use at TTN NY). Using 0x01010101010101 avoids endian issues.

This is NOT a locally administered address and should not be used or suggested (and it’s not actually 8 bytes either). I know this because I read this post:

DevEUI for non-hardware assigned values

You’ll have to judge whether you want to use a random ID. However, the definition of EUI-64 allows for this. The definition is given in chapter 8 of the IEEE-802 spec (freely available at http://standards.ieee.org/getieee802/download/802-2014.pdf). In section 8.2, they describe the u/l bit (bit 1) of byte 0 of EUI-64. If you set that bit, you have a “locally administered address”. Bit 0 always has to be zero for addresses. So a legitimate way of generating a random address, with very low proba…

Please enjoy the irony! I find this tool useful: Random EUI or Key generator

The OP managed to stumble upon all 2’s which is OK.
