Re: Can not program ESP-S3 with Flash Download Tool

I tested it with a board with the firmware already loaded through my IDE.
After I upload using flash tool the code doesn't start up.
Are my addresses maybe wrong?

Re: ESP32-S3: GPIO0 pull-down Issue

I just moved pins around and kept GPIO0 for the programming only.

ESP32-S3 Bluetooth Image transfer

Good day, We're currently using the ESP32-S3 to receive an image to display. We've set up the ESP32 as a server and receive data from an Android app based on the BLE_UART example in Arduino IDE. The image is about 300kb and it takes a few minutes to transfer all of the data. Is there a better way to...

Re: ESP-S3 Uart

Thank you,

We have moved the pins and it worked, we just wondered why that specific pins didn't work as it should.

Re: ESP-S3 Uart

We are using pin 43 and 44, the two marked for U0RXD and U0TXD. They are also marked TX and RX on the dev kit.

Re: ESP-S3 Uart

Hi, I apologize for the unclear schematics. The IC on the right is the SIM7600. The SIM7600's UART is 1.8V. For the TX of the sim7600 to the RX of the ESP we used the voltage level shifter as per the SIM7600 datasheet: lvl shift.png The problem is that the low bits to the ESP only pulls down to 2.8V...
