large TEXT as a publish starts to not obey a new line

[riwalker]

What did I do

try and publish large data, using '/' as a new line esp_mqtt_client_publish(mqtt_client, "/menu/dmx", "1 - UDP - Send DMX frame\ 2 - UDP - Send DMX RAMP 4 colors\ 3 - UMAC - Send DMX frame\ 4 - UMAC - Send DMX RAMP 4 colors - 5B\ 5 - UMAC - Send DMX RAMP 4 colors - 400B\ 6 - UMAC - Send BLANK all LED\ 7 - Reset STATs\ 8 - Get STATs\ a - Set Default PLC Setup\ b - Set PLC Modulation type\ c - Set Min/Max Intra-Frame Time\ d - Discover Nodes\ n - Send message to node x\ u - Unicast - Multicast Address\ v - START Unicast sACN Transmit\ w - STOP unicast sACN Transmit\ x - START Multicast sACN Receive\ y - STOP Multicast sACN Receive", 0, 0, 0);

What happened

see here (it works for the first 6 lines, then 7 & 8 go crazy, then it works again !?

Expected

all lines should align

Environment

• OS: WIn11
• MQTTX version 1.9.10

Hi, thanks for reaching out. I've tested locally via CLI and the desktop app, and everything works well. Please take a look at the attached images for reference.

Check the data format on your publishing side. To verify its accuracy, try printing or logging the data before publishing. Thanks for your understanding.

Im sending as rawtext

The / symbol is supposed to be a new line

So in MQTT, any format here ?

I just moved the page separator, and it gets worse

1. MQTT supports any data format, including UTF-8 text and binary data.
2. Using "/" as a separator is not a standard practice.
3. When MQTTX receives data and converts it to plaintext, it interprets it using UTF-8 encoding for standard text parsing.
