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.

Deep sleep power consumption external vs internal RTC

From a power consumption point of view is there any difference using the external RTC source instead of the internal?

ESP-ADF and Mongoose OS

Is it possible to use ESP-ADF with a 3rd party operating system like Mongoose OS? Or because they are both built "on top" of ESP-IDF does using one block using the other?

What is the ESP32-WROVER-B?

I see the ESP32-WROVER-B part listed on the Espressif documentation page (https://www.espressif.com/en/support/download/documents) but it does not bring up any documents and I couldn't find anything about it searching online. I am starting a new design around the ESP32-WROVER so I am curious if this...
