Re: ESP32-WROOM-32D/E deep sleep current consumption?
To try and find this answer myself I populated one of my PCBs with just the ESP-WROOM-32 module and the minimal components around it and then ran the "deep_sleep" example code from IDF 5.1.1. With the module in the deep sleep state the PCBA was consuming 44uA. For comparison when the module is held ...

ESP32-WROOM-32D/E deep sleep current consumption?
What is the expected Deep Sleep current consumption of the ESP32-WROOM-32D (or E) module? In the datasheet I can only find reference to the ESP32 chip that its sleep current can be as low as 5uA. I cannot find the same information for the module. Also if the numbers are different between the D and E...

Problem with ESP-Jumpstart Remote Control (Cloud) Example
I am working through the ESP-Jumpstart examples and I've run into a problem at the Remote Control example. When I try to use the cURL command to read the device state or change the state I always get a response like this (this is from a read attempt): % Total % Received % Xferd Average Speed Time Ti...

ESP-LyraT-Mini V1.1 documentation?
Is there documentation and a schematic available for the ESP-LyraT-Mini V1.1? I purchased the Mini V1.2 and I would like to use it to run examples from both ESP-ADF and ESP-Skainet but currently in both those frameworks only the Mini V1.1 is supported. I built the ESP-Skainet Get Started example and...

Re: ESP32 with Alkaline Batteries
I am working on a project where I plan to use 2 AA size Alkaline or Ni-MH batteries. I am using the TI TPS613221A to boost the voltage up to 3.3V. Per the datasheet I am using the part with an external schottky diode for higher output current operation. I just got in my hardware and haven't done muc...

problems with pipeline_bt_sink example with latest ADF
I recently pulled the latest ESP-ADF $ git describe --tags --dirty v1.0-108-g7d6f6ce-dirty and now I can no longer successfully run the pipeline_bt_sink example on my LyraT V4.3 board. With no change to any of the Menuconfig settings (which by default has Bluetooth for BLE only) the program runs but...

Re: max size of filename to save on sd card
Hi I am running into the issue of file names over 8 characters not working. I am modifying the sd_card example from the IDF and I am using version v3.3-beta1-328-gabea9e4c0 of the IDF. In the menuconfig I changed the option within FAT Filesystem Support to enable long filenames (I tried both heap an...

Re: Deep sleep power consumption external vs internal RTC
Thanks that is a good point. I guess my real question is for all of the circuitry within the ESP32 being clocked by the RTC during deep sleep mode is there any difference in power consumption based on whether the internal or external RTC is used. Subtracting the power drawn by the RTC itself.
