What would be the certification cost for developing small volume Zigbee or Matter+Thread applications using nRF modules and nRF Connect SDK? Is this eligible to certify via Certification Transfer Program (https://csa-iot.org/certification/transfer-program)? I think this is the low-cost path to the market. Please note that the intended application does not included in the samples, therefore it should be developed from Zigbee or Matter templates.
Does nRF Connect SDK support Zigbee Pro 2023? Is this increases the cost?
