My team and I are designing an automotive security box, and we have to design a key to unlock the box.
The key needs to :
-Work without buttons
-Last at least 1 year with a 210mAh battery
-Be secured (send rolling messages for example)
I saw in the Smartbond Product Family presentation document of June 2020 that the DA1469x is a good choice for Automotive Keyless entry, so are there some reference designs for hardware and software that could fit my requirements ?
Thank you in advance.
