Re: OTA: prevent stealing the firmware
If you wish to prevent the firmware file from being downloaded from your HTTPS server, then you could add client authentication to your devices. This means that only an HTTP client with correct authentication is granted access to the file. I know of two authentication mechanisms that the ESP IDF HTT...

Re: What is the latest version of the ESP32 chip and where can I buy a Devkit that uses it?
I managed to get an ESP-DevKitC-32E from TME a few weeks ago, but they're out of stock now. https://www.tme.eu/ee/details/esp32-devkitc-32e/muud-arenduskomplektid/espressif/ In a pinch you can order their last ESP-DevKitC-32UE which has the same chip but comes with an external UFL antenna connector ...

Re: how many bytes are read with uart_read_bytes()
Where do you see the overflow, in your own data buffer or UART FIFO buffer? If it's your own buffer overflowing, your UART handling is probably buggy. Can't tell without seeing your code, but I notice that you re-use the variable length to hold both number of bytes available and number of bytes read...

Re: The device can't connect to the mqtt server after the certificate has been changed on the server
What is the relationship between DigiCert and TrustAsia ov TLS Pro Ca? Why the DigiCert Global Root CA on my device can trust many different certificates that signed by TrustAsia? The DigiCert CA is a root certificate, trusted globally because everybody agrees so. It is used to issue the TrustAsia'...

Re: The device can't connect to the mqtt server after the certificate has been changed on the server
Is there a "general" certificate on the mqtt device, after using this general certificate on the device, no matter how the certificate on the server is updated, the device can normally connect to the mqtt server. Does this "general" certificate exist? Where can I get it? What you call "general" cer...

Google IoT client's memory limiter conflicts with ESP-IDF heap corruption detector
Hi! I'm using the excellent Google IoT Core client port from https://github.com/espressif/esp-google-iot. The CMakeLists.txt in this project enables the memory limiter (-DIOTC_MEMORY_LIMITER_ENABLED). This option seems to conflict rather badly with ESP-IDF v 4.1 heap corruption detection (enabled by...
