Re: Disabling BT controller does not lower consumption

I solved my problem. In fact the problem did not really exist. The power source, I was using when measuring consumption was not the same as the one I'm using for developing and debugging and It was not able to deliver enough power when BT controller starts (peaks seem as high as 280 mA), causing a b...

Re: Wrong ULP Consumption ?

Hi,

What kind of board are you using ? I made some tests with ULP (I tried the ULP example in the SDK) and I managed to reach around 15uA with a bare ESP-WROOM 32 (without external electronic, except pull-up resistor on EN pin). With ESP-WROOM dev kit I was not able to get below 1-2 mA.

Disabling BT controller does not lower consumption

I'm trying to develop a Bluetooth beacon, that broadcasts for a few seconds (less than 10) and then goes into deep sleep until it is awaken by an external event. Unfortunately, consumption remains very high even in deep sleep mode. I developed the smallest possible code to try to show the problem (s...
