The recommended antenna design for optimal performance is a 1/4 wavelength monopole antenna with a 50-ohm impedance. The antenna should be placed at least 10mm away from the module to ensure optimal radiation patterns.
To configure the module for BLE mode, set the module to Command Mode by sending the '$$$' command. Then, send the 'SBLE' command to set the module to BLE mode. Finally, configure the BLE settings using the 'SBL' command.
The maximum transmission power of the RN4678-V/RM111 module is +4 dBm (2.5 mW). However, the transmission power can be adjusted using the 'SP' command to comply with regional regulations.
To update the firmware of the module, use the Microchip Technology Inc. provided firmware update tool and follow the instructions provided in the user manual. Ensure that the module is in Command Mode and connected to a PC via a serial interface.
The operating temperature range of the RN4678-V/RM111 module is -40°C to +85°C. However, the module's performance may degrade at extreme temperatures, and it is recommended to operate the module within the recommended temperature range for optimal performance.
