Hello Erik,

Thanks for your quick reply.

1. I use the right UID instead XYZ (EJi)
2. I think it's not a quoting issue because when I don't put correct quotes, I get:  

   {"_ERROR": "Could not parse payload for write_frame call of dmx_bricklet EJi as JSON: Extra data: line 1 column 4 (char 3)"}

   I also have a Segment Display 4x7 Bricklet and use similar synthax for function "set_numeric_value" and it work well.

My MQTT bindings version is 

tinkerforge_mqtt 2.0.15

I try other function like "get_dmx_mode", "read_frame", "set_dmx_mode" and "get_dmx_mode". It work perfectly. Here is output of "get_identity":

{"uid": "EJi", "connected_uid": "Lnk", "position": "a", "hardware_version": [1, 0, 0], "firmware_version": [2, 0, 3], "device_identifier": "dmx_bricklet", "_display_name": "DMX Bricklet"}

Thanks for your help

Hello there,

I am working with bricklet DMX. I need to use it as DMX mode master and MQTT API.

Unfortunately, when I publish on topic "tinkerforge/request/dmx_bricklet/XYZ/write_frame" a message with value "'{"frame": [255,128,0]}' "

I get message "_ERROR": "required argument is not an integer (call of write_frame of dmx_bricklet XYZ)" on topic "tinkerforge/response/dmx_bricklet/XYZ/write_frame"

It work perfectly with Brick Viewer.

My setup:

Hardware: DMX Bricklet with FW 2.0.3 on HAT Brick FW 2.0.2

MQTT brocker: mosquitto version 1.6.10

MQTT Client: MQTT-Explorer 0.4.0-beta

Do you know if do something wrong? or if is it a bug?

Thanks in advance for any help.
