Guru Meditation Error during Cellular Firmware Update with ESP-IDF: Seeking Assistance

Hello ESP32 community, I am currently working on a project where I need to perform firmware updates over the air (OTA) using a cellular network. The chipset I'm using is ESP32S3. However, I am encountering a Guru Meditation Error during the OTA process, specifically within the esp_ota_end() function...

Re: UART software flow control in ESP32S3

Yes, local file system here means file system developed on the internal flash memory of ESP32S3. Thanks for the idea, I will try using the raw partition and reduce the baud rate. My primary application is to write in the raw partition but I want to check the data integrity first by downloading the f...

UART software flow control in ESP32S3

I'm using an ESP32S3 chip and trying to implement OTA through a cellular modem. The size of the bin file is 1250KB. The cellular modem has an AT command that downloads all the content in one go. Since there is no option to read it in chunks and there is not enough RAM to hold that 1250 KB of data. S...

MTCK and MTDO pins in ESP32S3

Hi, I'm currently working on a project using the ESP32-S3 chip, and I've decided to use MicroPython for my coding. In my project, I have connected GPIO 39 and GPIO 40 to relays for various operations. The ESP32-S3 datasheet designates GPIO 39 as MTCK and GPIO 40 as MTDO, which are typically used for...

Fat32 file system corruption on internal flash of ESP32S3

I am using an [ESP32-S3](https://www.espressif.com/sites/default/files/documentation/esp32-s3_datasheet_en.pdf) chip with 8 MB internal flash. Out of which 4 MB is for the FAT32 file system. I read and write files every 30 min into the file system. I am also using the wear leveling library that is a...

ESP rain maker app using micropython

Hi, I'm using the esp32s3 chip for development. I want to control the device using the Rain Maker app. I am using Micropython for programming the device. Did ESP provide support for the Rain Maker app in Micropython ? There is a page for the ESP Rain Maker app in Micropython: https://docs.espressif....

Scanning MAC IDs with weak signal strengths

Hi, I'm using ESP32S3 to scan the MAC IDs of the surrounding routers. So when I compared it with other devices with different MCU the ESP32S3 is ignoring the MAC IDs with weak signal strengths and the values of the signal strengths of the scanned MAC IDs are less compared to the values of the signal...

Limited number of KEYS for NVS partition

Hi, In the partition table, I assigned 32KB to NVS in ESP32S3, but while using the NVS I tried to create 1000+keys with the value of 2 bytes and I got an error saying NOT enough space for storage. Considering each key to be of 2 bytes it accumulates to be only 2000 bytes. As per my understanding, it...
