Can WFM200S Series 2 Wi-Fi Transceiver Module support Linux and PTA with EFR32 Zigbee NCP?
I understand you would like to connect both a WFM200 Wi-Fi transceiver and an EFR32 in ZigBee NCP mode to a Linux host. If this is the case, you can wire the PTA signals between the EFR and the WFM200 to improve coexistence. Note that we recommend you connect the EFR32 NCP and WFM200 using different buses (SPI for the EFR32 and SDIO for the WFM200 for example).
Our distributor replied us that SL doesn't recommend using WFM200. In our case, we will use UART for SPI and it's OK to use SDIO for WFM200. Can you confirm there is WFM200 Linux driver to support PTA with EFR32 running EmberZnet?
The WFM200 is still recommended for new design. however the comment might related to a change in OPNs (WFM200S022XNx2 to WFM200S022XNx3). You can check the documentation below for additional information:
