SPI-not receiving correctly

Hello,

I am connected to wizfi through android and MCU. When I power up the devices MCU+wizfi then when wizfi associates with my home wifi it raises to 3.2v the GPIO14 and never stops. It only makes GPIO14 to 0v when I connect the android device to wizfi.

If you look the photos then you will see that some of the data FROM wizfi are going to my MCU OK but almost all afterwards are scrabbled!
I can get the words connected, up link and some others but then the wizfi sends characters that make no sense.

The word “hello” is written by me it is just to know that the program is running.

Any ideas?

Should I change any configuration details?

IS ANYONE EVER MANAGED TO COMMUNICATE WITH WIZFI250 THROUGH SPI?

Thank you,

Best Regards,

Andreas Achilleos
