Maybe here in the ADF forum are some Lyra- T users.

I’ve a Lyra- T( using WROVER- B) and I’m trying to get JTAG debugging working on Windows. I’ve tried both VSCODE ane decline. Both detect the chip via JTAG, but I do not get any step further.
Anyone here having more success, or even can confirm it must be possible with the Lyra- T?

    The JTAG debugging issues I was having when using VSCode, ESP-IDF Extension, and ESP-PROG *may* have been caused by the ESP-OpenOCD v0.11.0-esp32-20220411. When I replaced it with ESP-OpenOCD v0.11.0-esp32-20220706, I was able to flash via JTAG and Start/Stop debug session without seeing any errors.

Is it possible to use this device as a ESP32- S3 development kit, or is it limited to configuring the GPIO pins and integrating with the app?

    It can be used as a ESP32- S3 development kit, you can see the PMOD marker to get the available GPIO. However, configuring the GPIO does not need through the app, If you tone development commodity. The mobile app is used with the figure- in firmware.

While using ESP32-S3-WROOM-1-N8R8 module for my application. I used GPIO20 as a GPIO input for switch application. I have used external pull up for digital high or low. But in that pin ,there is an inbuilt internal pullup. But it isn’t mentioned in datasheet.

Kindly suggest how to change that pin to Hi-Z state.

    No, If you want to use Arduino for development, the only way to use such functionality is to use Arduino as IDF component.

    “SW_CPU_RESET” is the software reset log. For example, calling the “esp_restart()” API will print this log.

We will use a ESP32-C3FH4 in a project. We will not have a external flash. Is it possible to use all GPIO’s including the ones dedicated to flash SPI as plane I/O’s?

We are facing an issue while connecting the ESP32 device with the Android mobile using ESP32 Wifi. We have tried to connect the mobile device and ESP32 manually by using ESP32’s SSID and password. It seems to be, when the ESP32 signal strength is good/excellent then the android mobile get connects to the ESP32.
And when the ESP32 signal strength is poor then the android mobile not connects to the ESP32. We have tested the issue on various android device version (6.0, 6.0.1,7.0, 8.0, 8.1 etc.) But, it sometimes works or sometimes may not work due to the poor ESP32 signals.

Can anyone please let us know the behavior of the ESP32 is correct?

    Are you setting ESP32 in AP mode, and the trying to connect your smart phone with the ESP32 SoftAP ? 2 meters shouldn't get the signal poor like that. Can you read the RSSI from the phones ? Which hardware are you using? Could it be that the antenna is missing ?

When using a softphone on my PC, registration to Asterisk (on my laptop) registration works fine (also calls work).
When using Espressif ESP32, it registers but says Unreachable when I have put Qualify=yes in Asterisk.
When I change qualify to no, reload asterisk, exit, then change again qualify=yes and reload asterisk, then my Espressif ESP32 shows OK/ms, and can call android/iphone. (only voice if I call from the phone to esp32, not from esp32 to iphone. But that is the next problem to solve).
Could this be a bug in ESP32-VOIP SW ? Or how can I get around this problem ?
