In the overview page, the product is claimed to run for a year on two AA batteries. After reading the datasheet, I'm having doubts but hopefully somebody can prove me wrong.
I'm going to be building an IoT solution with the CC3200. One of the core requirement is that the chip has to be consistently connected to the cloud server (Over MQTT protocol) so that other devices can control the microcontroller as responsive as possible.
According to the current consumption section of the datasheet, the current consumption seems to be in between 50 to 300 depending on your modes. Since the microcontroller has to stay connected with the cloud, I'm assuming I need to look at MCU/NWP active rows. Assuming I'm using lower power level, it seems to be 189mA for TX and 59mA for RX so in total, 248mA.
So two AA batteries should have around 3000mAH, which means I only get 12 hours of battery life. Now of course, I realize the device won't be transceiving at every conceivable moment, but even stretching the above calculation, I can't imagine I will get longer than few days of battery life.
Are there anything I'm overlooking? Please let me know. Thank you.
