Oh wow, this is fantastic! Congratulations!
Can you quantify the 'low signal level' already?
The antenna in the microSD card is obviously tiny, it would be interesting to
understand how low the signal level is and whether it is enough for actual
use of the card, say at the typical home or in a public hotspot.

We will not win any distance or noise competitions with this card, that's
for sure. But hopefully it's enough for normal use...

Anyway, step by step - the news that you got some data through is really
encouraging!
So far Renesas has not yet officially clarified the redistribution license
for the binary firmware file. I need to ping them again about this...
Thanks a lot, Best Regards,
Wolfgang
