Just checking in if the latest ESP-IDF has support for less power consumption during BTLE?
kind regards

Re: BLE low power status
Thanks billiam. While 80-100 is crazy, 20mA is still very high for a BLE device. It sure would be nice to get closer to 1.5mA, which other devices are doing quite effectively.

Re: BLE low power status
Our tests show an ESP32 with active bluetooth module runs at around 100mA, which is several orders of magnitude greater than a similar BLE focused chip, at least, when we played with this 6 months ago. I know reducing power consumption was a priority, so hoping some progress has been made in the mea...

BLE low power status
Hi team, Just a quick check to see where we are up to with BLE low power consumption modes. The last time we checked, about 6 months ago, there wasn't a way to get our favourite chip doing BLE on battery power alone. Has this changed? We would love to use the ESP32 for our next product with the fabu...

Re: MSYS2 is slow on Windows 10
I concur, the pauses (not sure what it's doing) do slow down the development process.

Re: I2S-parallel example: Drive a 64x32 display
Taking Sprite_tm's work and adding extra colour(s). image1 (2).jpeg Jinx is a ... well it's a little hard to describe. It's a LED performance application that allows you to send fun graphics to LED and other lighting devices. All the processing is done on a PC and then it sends frames to the device....

Yes, they daisy chain like one long shift register. Of course, the software needs to change at that point.

Spectacular Sprite_tm! BTW #include "driver/gpio.h" required in app_main.c and i2s_parallel.c to compile. http://www.embeddedadventures.com/datasheets/ABCD.png On my display, despite leaving #define DISPLAY_ROWS_SWAPPED 1 the display is fine... and looking at the above output, the ABCD lines are in ...

Re: Timer group performance
Thanks ESP_igrr. I switched to single core mode and ... it's rock solid. No flicker. Switch the other core on, and it flickers, about every 10 seconds it goes through a flickering state for a second or so and then returns to normal. However since sprite has been able to outsource the entire driving ...
