Frequently Asked Questions

What is the default communication interface and how do I configure the E72-2G4M02S2B module?

The module uses a UART serial interface (TX, RX pins) for communication with a host microcontroller. It operates on a default baud rate, typically 9600 or 115200 bps, which can be reconfigured via AT commands. You send ASCII-formatted AT commands (e.g., AT+VER?) through the UART to query firmware version, adjust RF parameters like transmit power, or modify the connection interval for optimal power savings in your BLE application.

Can I attach an external antenna to this module, and what type of connector does it use?

Yes, the E72-2G4M02S2B module includes a footprint for an IPEX (also called U.FL) connector, allowing you to solder a compatible mating connector to the board for an external antenna. Using a higher-gain external antenna via the IPEX port can significantly improve range compared to the integrated PCB antenna. Ensure the external antenna is tuned for the 2.4GHz band and has a 50-ohm impedance for proper RF impedance matching and optimal performance.

What are the power supply requirements and sleep current characteristics for battery life estimation?

The module requires a stable 3.3V DC power supply. While active, it draws approximately 2mA in receive mode and 11mA during transmission. For long battery life, you must utilize the CC2640's built-in low-power modes via firmware. The module supports various sleep states where current consumption can drop to microamps. You need to implement connection intervals and advertising parameters in your BLE firmware stack to maximize sleep time and minimize average current draw for your specific sensor reporting rate.
