CC2538 SoCs are Cortex-M4 based SoCs by Texas Instruments for 802.15.4 PAN networking, especially for Zigbee communication using their Zigbee Stack solution. It also is a solid foundation for hobbyist-grade solutions involving Zigbee communication, especially for running a self-implemented Zigbee coordinator (often called "Zigbee gateway" in commercial distribution of similar tech). Software-wise, this is usually done by running "ZNP" (Zigbee Network Processor) firmware on the SoC and using a separate controller/computer to act as the "ZAP" (Zigbee Application Processor). In a hobbyist setting, the former is usually a cheap module from china containing the chip, capacitors and an antenna or antenna connector, while the latter is e.g. a Raspberry Pi or an Intel NUC or whatever floats your boat. The API between both components is specified and so the software side on the ZAP does not need to bother with Zigbee communication states but can act on a
