Hello, I use the cards I created with ESP8266 and Hive MQTT with CA certificates without any problems. Is CA certificate required for ESP32? I couldn't find an example of a CA certificate for ESP32, can you help me?

Since Arduino IDE 2.x releases the BIN flashing become some more sophisticated. The OTA file is not a single BIN type one anymore.
For example, the "Aygedzor_copy.ino" 's compiled binary consist of 4 files and flashing arguments looks this:
Code: --flash-mode dio --flash-freq 80m --flash-size 4MB
0x0 Aygedzor_copy.ino.bootloader.bin
0x8000 Aygedzor_copy.ino.partitions.bin
0xe000 boot_app0.bin
0x10000 Aygedzor_copy.ino.bin

Hi,
I wish to know if it's possible to send the Android devices sensors values to a server different from Emulator.
Thanks in advance.

| How to use a variable's value to create a dynamic MQTT subscription topic? |
|

Hello everyone,
I'm trying to create a dynamic MQTT subscription topic that is built using the value from another variable, but I can't seem to find the correct syntax.
Here is my setup:
- I have a variable (ID: C2_V0) that successfully reads a device's serial number from an MQTT topic. Let's say the serial number it reads is "MySerialNumber123". This works perfectly.
- I have a second variable (e.g., "Charger Current") that needs to subscribe to a topic that includes this serial number. The topic structure I need is: Y/<serial_number>/AC/CHARGER/Current.
To achieve this, I tried to set the subscription topic for my second variable like this:
Y/$C2_V0.value/AC/CHARGER/Current
However, this doesn't work. It seems the app is not replacing $C2_V0.value with the actual serial number ("MySerialNumber123"). It treats it as a literal string.
Is it possible to dynamically build a subscription topic using the value of another variable? If so, what is the correct syntax I should use?
Thank you for your help
