Re: What would you like to see in The Next Chip?

Lower power! ESP32 is already good but the sleep-mode power consumption could be lower. Pulse counters available in the RTC domain. So we can turn off the main processors and (optionally) ULP leaving the pulse counters operating and able to wake-up the ULP/main CPU on a threshold or condition. Meter...

Re: Bluetooth royalities for distribution

Yes you *should* pay: https://www.bluetooth.com/develop-with-bluetooth/qualification-listing/qualification-listing-fees Bluetooth SIG membership is free. You should 'declare' your product; I don't think 'qualification' is needed because it's the ESP32 module that you're using, not your own design. T...

Re: Pulse Counting and sleeping

Wow! Super support, I wasn't expecting code! :) I'll give the deep-sleep pulse counting a whirl. The pulse frequency changes depending on location and consumption; pulse length can be constant (electronic meter) or changing (mechanical meter). So I'll have to build a current profile with a variety o...

Re: Pulse Counting and sleeping

Many thanks, ESP_Sprite. OK, that's a little disappointing. The pulse counters look pretty awesome - shame it looks like they're too power hungry to be used in a battery powered sensor. You say the ULP can be used - would that be polling the GPIO / ADC or some kind of GPIO interrupt? I didn't think ...

Pulse Counting and sleeping

Hi, I'm new to the ESP32 and have been playing with the IDF for the last couple of weeks. I'm trying to get the ESP32 to run for a long time on a couple of cells to take regular measurements (ADC and/or count pulses), log them and then send the data daily. I have had some trouble understanding the p...
