The CYBLE-224110-EVAL is not a range extender, it's a PSoC 4 BLE device of it's own with a dedicated, internal, power amplifier to increase its range.
You can connect it to the 062-BLE device via e.g. I2C, SPI, UART but they are otherwise independent devices and the BLE stack would still run on the CYBLE-224110 modules, not on the PSoC 6. You could then in theory program the CYBLE-224110 as a "modem" for the PSoC 6.
That said, unless you want to use a particular feature of the PSoC 6 I don't really see much point in such a configuration.
It is sold as a range extender anyway for the dev kit 042-BLE. CYBLE-224110-EVAL EZ-BLE™ PSoC XT/XR Evaluation Board | Cypress Semiconductor
I usually develop pointless stuff - never mind . However, here I seriously need to extend the range of the 062-BLE Dev Kit. I just wondered if it will connect as simply to the new BLE Dev Kit as it does with the 042-BLE.
