I see no response from Espressif staff, so I decided to do some investigation by myself. Apparently it seems ESP32C61 and ESP32C5 have very similar BLE IP cores (likely the same). I copied static library libble_app.a from C5 directory to C61. And it seems the project works now. Position calculation ...

Hi,

I am trying to use CTE feature. There are two example programs - periodic advertisement and periodic sync with CTE. Both work fine on ESP32H2. Unfortunatelly on ESP32C61 bogus IQ samples are returned - all I/Q values are -128.

Do you know where the bug is? Software, or hardware? I am trying ...

I observed weird phenomenon while entering deep sleep mode. GPIO line is configured as wakeup input, low level active.

a) When high level is applied to GPIO input, ESP enters deep sleep mode correctly. It is also woken up as soon as low (active) level appears at the input.

b) When there is low ...

OK, I managed to prepare code, which reproduces the problem. Please set up sdkconfig in such way that line endings are LF (driver won't do conversions) and try the following code:

#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>

void app_main(void)
{
while(1)
{
printf("Text 1\r\n ...

Hi,

I observed occasional phenomenon - some (not all) newline characters are lost. Quick debugging with strace proved all data delivered to /dev/ttyACM interface is complete and correct, there is a bug in python code. I made some investigation and found problem in tools/idf_monitor_base/serial ...

So I managed to find cause. It seems problem occurs when ESP ROM log to UART is disabled (UART_PRINT_CONTROL e-fuses burnt). If ESP ROM log is running - RF test firmware also works properly.

Hi,

I have weird problem with RF test mode on ESP32C3. I am using ESP RF Test Tool, version 2.8. On ESP8266 (ESP-WROOM-S2) and ESP32 (ESP-WROOM-32) it works. However, on ESP32-C3 (ESP32-C3-MINI-1 module on ESP32-C3-DEVKIT-1), there is completely no output on management UART. Could you please help ...

Hmm single digit mA would be excellent for me. Currently I have ~78mA while Bluetooth is constantly (100% duty cycle) listening for beacons.

Hi,

In ESP32-C3 datasheet there is current consumption data (tables 15 and 16). Unfortunatelly I can't find data related to Bluetooth Low Energy. Do you have it?

To be honest, I tried to start two applications:
1. Wi-Fi performing continuous passive AP scan (permanent Wi-Fi RX)
2. BLE passive ...
