Is 3-wire or 4-wire coexistence with non-Cypress BLE modules supported?

Should specific pins be reserved for this feature or can it be mapped to any GPIO?

Thank you

The 43907 part doesn't support 3-wire/ 4-wire coexistence.  4-wire is very much deprecated and 3-wire support is reduced to combo chips like 4343w.

Could you mention the use case / project detail that you are working on.

If this is an feature request for 43907, then this has to come through the local FAE/Sales.

Unfortunately that document doesn't quite answer my questions. It indicates that Cypress-proprietary SECI only works with Cypress Bluetooth devices. The document mentions the 3-wire coexistence, but in reference to Zigbee specifically. I'm not clear if there is a reason that BT/BLE is omitted.

Also, the document hints that 3-wire coexistence is only available on certain GPIOs, but only lists the pins for a single device (CYW4343W). It does not indicate which GPIOs are available for this feature on the CYW43907.
