I am trying to get the GCI interface working between the 43907 based 1gc and the 20707 based cybt353027-02.  I have flipped the low bit in the board flags for the 1gc nvram.txt and I can see the gci messages being sent out.  I have also called wiced_bt_coex_enable() in the bt firmware.

I have j6:38 and j6:39 (rf_sw_ctrl_8, and rf_sw_ctrl_9) of the 43907 dev board connected to gpio_5 and gpio_6 (of the cybt353027-02.

The bluetooth board doesn't seem to be enabled for gci as there is nothing coming out of the bluetooth seci_out.

Am I missing something?

Thanks

Hello,

As per the internal interactions seems like Coex pins are not brought out for CYBT_353027 module.

I would suggest you to use CYBT_343026 module (https://www.cypress.com/documentation/datasheets/cybt-343026-01-ez-bt-wiced-module ) which uses the same base die (CYW20706) if you are in early stages of product evaluation.

It has Coex pins - GPIO_ 6 & GPIO_7

Extremely Sorry for the inconvenience caused.

Thanks & Regards,

Anjana
