To connect the ESSYS BWR-Y89359 WiFi-Bluetooth Combo Module to your device, you will need to follow these steps:
1. Identify the host interface pins for Bluetooth and Wi-Fi on your device. The Bluetooth host interface consists of four pins: BT_UART_TXD, BT_UART_RXD, BT_UART_CTS, and BT_UART_RTS. The Wi-Fi host interface consists of six pins: SDIO_CMD, SDIO_CLK, SDIO_DATA0, SDIO_DATA1, SDIO_DATA2, and SDIO_DATA3.
2. Connect the Bluetooth host interface pins on the module to the corresponding pins on your device. This will enable communication between the Bluetooth module and your device.
3. Connect the audio interface pins for Bluetooth on the module (BT_PCM_CLK, BT_PCM_SYNC, BT_PCM_IN, BT_PCM_OUT) to the corresponding audio interface pins on your device. This will allow audio data to be transmitted and received through the Bluetooth module.
4. Connect the Wi-Fi host interface pins on the module to the corresponding pins on your device. This will enable communication between the Wi-Fi module and your device.
5. Connect the Bluetooth/Wi-Fi On/Off and Reset pins (BT_REG_ON for Bluetooth, WIFI_REG_ON for Wi-Fi) on the module to the appropriate control pins on your device. This will allow you to control the power and reset functions of the module.
6. If desired, you can connect the module to wake up the host device by using the Controlled by Module to wake-up Host feature. This is optional and may require additional configuration.
7. If desired, you can connect an external LPO 32.768KHz Clock to the module. This is also optional and may require additional configuration.
Please refer to the ESSYS BWR-Y89359 WiFi-Bluetooth Combo Module User Manual for more detailed information and pin configurations.
