Same MAC Address in several CC3000MOD

Hi loris,

You can set the MAC to whatever you want using the set mac address API: http://software-dl.ti.com/ecs/simplelink/cc3000/public/doxygen_API/v1.11.1/html/de/dcc/group__nvmem__api.html#ga171c47c64f3d8ee8c650c7dd837e835c

I've seen this MAC address before, this occurs when you fail to update the firmware on the CC3000 properly.

First you must read the MAC & param table and keep it in memory, rewrite the FAT , reset the module, write param table back and then write the MAC address back. I've had a problem where I hung waiting for the reset to complete. this meant the fat had been rewritten but no MAC or param table had been written back, querying the MAC gave me a MAC address full of 0x55's too. So you just need to make up a new one and write it to the eeprom. 

The original MAC address is lost unless you've kept a note of it.

Thanks for the replies.

Recently I pay more attention upgrading patch on cc3000mod and it seems that the problem is no longer present, so I suppose that I have done some mistakes in the past doing it.

I'll try to write a new MAC working on the API.

Thanks again.
