Re: Touch sensors are a little less sensitive in the first 30s after wake from sleep

Can someone _please_ confirm that calibration data (set by the app via touch_pad_config() and touch_pad_set_thresh()) is not being used while in deep sleep? This would explain why touch sensor sensitivity is lower during deep sleep, especially with a 2mm panel covering the sensors. If true, this wou...

Re: Touch sensors are a little less sensitive in the first 30s after wake from sleep

Please provide the version of idf you used. I was using v3.0-rc1 from 2018 Feb 21. I have now upgraded to v3.0.1 and this appears to fix the "less sensitive in the first 30s after wake" issue. I am not seeing this behavior anymore. This is great. However, while in deep sleep, sensitivity does still...

I mean while in *suspend mode. Haha.

No, not that I am aware of.

Re: Touch sensors are a little less sensitive in the first 30s after wake from sleep

Does the same thing happen with when you first power it up? Definitely not. The delay I describe above only takes place after wake from sleep. One other observation. When the device is in sleep mode, I usually wake it up by touching one of the sensors. It's really nice that this overall process is ...

Touch sensors are a little less sensitive in the first 30s after wake from sleep

I only notice this behavior when I use my touch sensors with a 2mm plastic panel on top. Proper calibration is very important in this configuration. But with proper calibration, things are working fine. And they do so all the time. Except for in the first ~30 seconds after wake from sleep. During th...

Re: Touch Enabled Deep Sleep Power is too high; please help

I did play with the measure timing and duty cycle and now have a responsive touch sensor on both inputs with only 10uA current. May I ask what values you are now using with touch_pad_get_meas_time(sleep_cycle,meas_cycle)? Default values appear to be 4096 (=0,027ms) and 65535 (=0,008ms) on my device...

Re: BLE-only power consumption

FYI: The BT(LE) drivers in esp-idf as of now aren't optimized for power yet, so while the hardware should support low-power modes, there's no software to use them yet. We're working on getting the needed changes, however. Has there been progress regarding BT-LE low-power modes? When will BT-LE conn...

Re: Red light is always on

My Wemos Lolin32 lite has also started flickering it's red charging LED a while back. I do not experience flashing issues, nor apparently any other issues related to this. But it is giving me the willies. Problem occurs on multiple Lolin32 lite boards. And it doesn't make a difference whether there ...
