I have used this mqtt library for esp8266 project.
And it works fine.
but when I tried to subscribe on multiple topic with same client, failed to subscribe.
so, This library can not support multiple subscription.

xtensa-lx106-elf/4.8.2/../../../../xtensa-lx106-elf/bin/ld.exe: build/app1.out section `.text’ will not fit in region `iram1_0_seg’

I tried to change length in ld flag and compile correctly device continuously reboot.
I use RTOS 1.4.0 SDK.

I have limited skills on C, and I’m trying to figure out how to output using printf the received message. I noticed that your code print one character at once (using the dsmg_putchar), but I’m having hard time to convert this to a usable string.

I will try that out and let you know. By the way, do you have a simple UART echo program for ESP8266? I am trying to read data on UART0 and echo it back to UART0.

Reading the UART fails somehow fails with a fatal exception 28. I am partially using the UART.c file from the UART_TCP_PassThroughDemo project.

Hi Ravi,
You can locate /ld/eagle.app.v6.ld, there is a section
MEMORY
{
...
irom0_0_seg : org = 0x40240000, len = 0x0fb000
}
Change len according to your module’s flash size. There are some sample values at the top of the file.

I tried compiling your code and I get the below error message:
I too am using the RTOS SDK 1.3.0. Can you please help me with this?

I have the Tuan implementation in my current project but I will look closely at your implementation for the future. Looking forward to the ESP32 as well!
