pytest is a popular testing framework for Python, and ESP-IDF build system includes some tests for the blink sample project.

"Bluetooth controller initialize failed: ESP_ERR_INVALID_STATE," typically indicates a problem with the Bluetooth controller during initialization. Please check your Bluetooth configuration settings.

The actual number of clients that can be reliably supported may vary. It depends on factors like network traffic, data throughput, and the processing power available on the ESP32-C6. I think you need to perform a test with your 50+ devices and see the performance.

Add a small delay between each refresh.

Please check the battery voltage with a multimeter. Maybe it's not sufficient.

Hi, what power supply are you using for the SIM800?

If possible, use debugging tools like oscilloscopes or logic analyzers to monitor the signals during the boot process. This can help identify any anomalies or timing issues. Since it's a custom board, you must check for short circuits or broken traces. You can check with a multimeter. You can make a...

The size of the coredump partition determines how much space is available for storing the core dump information. If the size is set to 64K, as you mentioned, it may limit the storage capacity for core dumps.

The error message specifically mentions "Cache disabled but cached memory region accessed," and it seems to be happening during the execution of the esp_ota_end() function.Carefully review the code related to flash write operations, especially in the esp_ota_end() function.

I assume the deep-sleep current consumption is the same for all versions of ESP32. That's why they do not specify anything in the datasheets. Let's see if the admins here say otherwise.
