I would suggest that while you could use the MAC address as a serial number, it is not a good idea
Why not? whats wrong with it?
When powered directly, without the dev board, power consumption is as expected 141mA@3V3 when idling with WiFi off.
Like i mentioned, I'm using a 2SP module on the development board with power being measured at the input USB cable.
According to the datasheet "Idle and WiFi turned off" should have a current consumption of 130mA at 3V3 (429mW), but when measured on the USB 5v on the eval board I'm getting 165mA(825mW). Could someone tell me why the power is almost double?
