I've purchased Cy5674 module, which gives option to connect antenna. On every picture was antenna together with module.
But when module arrived, they say: "sorry Antenna was too expensive for You".
Now I run two exactly same examples. One works (without antenna) other not.
I guess Cypress say wrong antenna. It will be a long, long story
We do not ship external antennas with this module. Can you provide more details about the issue? Which project does not work without antenna?
