1. Yes, you can have SIG client and server model on the same node/element 2. Vendor model does not have client/server model per se 3. You can have vendor "client" and "server" model on the same node (suggesting to use 2 different elements, not needed thou) 4. You can use the same vendor model as a "...

void (*MainPtr)(void*); MainPtr = (void(*)(void*))(FunctionAddr) ; //FunctionAddr is the Address of start of code from external source in IRAM MainPtr(NULL); //Execute code If this works, then maybe try to use some hack and call it from within a task created with xTaskCreate? Or maybe all works fin...

Looking i wireshark, sending request from ESP32 - ESP32 -> Huawei - a 66 byte Modbus/TCP package is send - Huawei -> ESP32 a 64 byte [ACK] is sent - ESP32 -> Huawei a 54 byte [FIN, ACK] is sent - Huawei -> ESP32 [ACK] - Huawei -> ESP32 [FIN, ACK] - ESP32 -> Huawei [ACK] This is the reason i suggest...

Here is your situation: - you can monitor device over USB or over UART, those are most basic options - you dont have UART, so that option is not available - you want to uninstall USB, so that option is also unavailable more advanced options are (you can also send message to enter bootloader mode): -...

You can manually enter bootloader mode with EN and GPIO0 pins.

As far as i know there is no such option, but you can choose to not erase entire partition on ota begin, just block after block during flashing (iirc). That should speed up ota start, but will slow down entire ota process.

Couple years ago ive been working with AWS-FreeRTOS, which has had support for OTA from aws. https://docs.aws.amazon.com/freertos/latest/userguide/freertos-getting-started.html Currently it seems to be deprecated, but i found this on freertos site, which i believe is worth to study: https://freertos...

Hi, i am not that much experienced as i would like, but i can tell you this: - yes, start with vendor model - broadcast is when you send message to address 0xFFFF (all nodes) - unicast, as you already know its when you are sending to unicast address(0x0001-0x7FFF) - group when you are sending to gro...
