The following precautions should be considered during designing with PCB antenna:
Do not place any electrical components or grounding in antenna area on main board and its better to leave this area blank on PCB. It is recommended to not place any electrical components within 10mm range of module antenna and not design any circuit or bond copper on main board under this area. Do not use the module inside any metal case or containers with metal painting. Keep the antenna of wifi module next to the edge of main board (as shown in Fig 5) during design of PCB to ensure better performance of antenna. Fig 5 BL3358-P Recommended PCB layout 4.4.

For devices with 3.3V power supply, you can directly connect the device UART port with module UART port according to the illustration in Fig 12. Fig 12 Circuit diagram (3.3V) If your device is powered by 5V, you can refer to the circuit shown in Fig 13 or design your own circuit for power conversion. The value of resistor can be adjusted according to actual circuit design. 5.2. Power Supply Requirement If an LDO is used to supply the module with 3.3V power, C1 capacitor can be considered to be used with 10u-22u; If a DCDC is used to supply 3.3V power, C1 capacitor can be considered to be used with 22uF. It is recommended to supply the module with power higher than 400mA to ensure enough power supply to the module and avoid power down during data transmission.
