Hello @nadirG,
Hope you are doing well.
My apologies, there may not be an application for Zigbee RCP. However, perhaps you could try to emulate a similar functionality using Zigbee Control Bridge as base. This Application Note provides a slave application that receives commands to control devices within a Zigbee network, allowing the master to bridge into a Zigbee network while servicing IPv6 devices or other protocols. This is done by using the Zigbee Gateway Graphical UI (ZGWUI) to interact with the Control Bridge to manage the network and the devices.
The ZGWUI is a C# application that acts as a PC host that communicates serially with the Control Bridge, and its functionality could be ported to a host MCU/MPU, allowing the host to communicate with the K32W061 using UART. For more information on this, please refer to JN-AN-1247 Zigbee 3 Control Bridge User Guide (inside JN-AN-1247 folder > Doc).
Regards,
Eduardo.
