No, unfortunately, ordering a Thingy:91, it was more a lottery, which version you get.

Anyway,if It's used now fro newer Thingies, then the question is answered for me.

Ok, so the EEPROM was not put into use before v1.6.0 according to our HW team. In v1.4.0 and v1.5.0 the FICR address is empty.

Were you able to get your hands on a v1.6.0?

Hello, no I did not get a response and then it went under my radar.

Will provide an answer by end of today or tomorrow.

Sorry for the inconvenience.

Any update?

Is that date in the EEPROM used? Or is that idea withdrawn?

Though it's more curiosity then a real issue; no need to hurry.

I'm happy, that the EEPROM is there at all and the most of it can be used for an application.

I was still not lucky with getting a v1.6.0 to test and the main benefit of reading the hw version would be to detect the v1.6.0 in order to omit the suspend of the 3.3V.

Hello, and sorry for the late response. The person who was supposed to provide an answer is out of office due to Christmas break. I will update you as soon as I get an answer from him.

Kind regards,

The v1.4.0 and v1.5.0 are the HW versions of Thingies 91 I tested.

Therefore I'm wondering, why the content of the EEPROM is the same.

A small update. The eeprom is intended for HW identification, however, I'm not sure what the status is. Will have an answer next week.

Kind regards,
Øyvind
