Re: Ideas to consume less current with less heat

HI

Just to complete my finds, I discovered that there is a register that controls the peripherals
DPORT_PERIP_CLK_EN_REG
reading from it I found that most of the peripherals when not used are off so seems that the module are already configured for minimum power consumption.

Re: Ideas to consume less current with less heat

Hi username Thanks for the links I will check on that. But I still want to dig on the Esp side, this blog http://iot-bits.com/ultra-low-power-design-esp32-10-tips/ on Item 6 he says that I can write to the DPORT register and turn off the peripherals that I dont use, this seems like an interesting th...

Re: Ideas to consume less current with less heat

Hi ESP_Sprite That would be my last option for two reasons, one is space with buck convertes I will need an inductor which takes lots of space and the second is interference, in my early prototypes I used a buck converter with an inductor and when I started using NVS (with Preferences library to sto...

Re: ESP-WROOM32 Bluetooth Signal Strength

Hello Toby In my current project I had some problems with BT and I found that the way you put the wroom module on your board or what else is close to it has a really big impact on BT performance. Check the esp32_hardware_design_guidelines_en.pdf it has some tips on how to place your board, In my cas...

Ideas to consume less current with less heat

Hello I have a project where I have to use a 12V power supply to power a wroom module in active mode with BT (not deep-sleep or light sleep), the problem is that my voltage regulator (UTC1117AL 3.3V Dpack) gets really hot. I was able to reduce some current consumption running at 80Mhz, now my module...

Can ESP32 runs at 40Mhz?

Hello

I saw in the power management documentation that we can control the clock, but it says that for ESP32 the values are 240/160/80 could I go lower then 80? Like 40Mhz?

Thanks

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

I would like: Hardware 1- A better ADC (more accurate) in my current project I had to add an external ADC because each esp32 had a different reading for ADC 2- Option to lower power consumption 20mA with BT (no sleep) Software 1- Better documentation more detail / explanation 2- More sample code wit...

Re: idf.py monitor --print-filter error

Hi roland

I found the problem, I am using version 3.2 of IDF but was looking at the docs for version 4.0.

The docs for version 3.2 is correct

Thanks

Re: idf.py monitor --print-filter error

I think that idf.py monitor --print-filter is wrong in the DOCs but I found

idf_monitor.py --port /dev/cu.SLAB_USBtoUART --print_filter "*:N" ./build/myproject.elf

That works
