The recommended power-on sequence is to apply power to the module in the following order: 1. VDDS (1.8V), 2. VDDA (1.8V), 3. VDDC (3.3V), and 4. VBAT (battery voltage). This sequence helps prevent latch-up and ensures proper operation.
To optimize Wi-Fi performance, ensure that the module is placed in a location with minimal interference, use a good quality antenna, and configure the Wi-Fi settings using the SimpleLink Wi-Fi API. Additionally, optimize the transmission power, data rate, and channel settings based on your specific application requirements.
The maximum current consumption of the CC3220MODSM2MOBR depends on the operating mode. In Wi-Fi transmit mode, the maximum current consumption is approximately 240mA. In Wi-Fi receive mode, it is approximately 120mA. In sleep mode, it is approximately 10mA.
To implement secure boot and secure firmware updates, use the Secure Boot and Firmware Update features provided by the SimpleLink Wi-Fi API. These features use cryptographic techniques to ensure the authenticity and integrity of the firmware and prevent unauthorized access.
The operating temperature range of the CC3220MODSM2MOBR is -40°C to 85°C. However, the module's performance and reliability may be affected at extreme temperatures. It is recommended to operate the module within the recommended temperature range for optimal performance.
