The payload is present in the "data" field as a base64 value

Code Block

language	json

"data":"AAAzMgGA"

The base64 value is converted to HEX and the output is decoded using the "decode_MLRT_HB_P_Uplink" function

The "decode_MLRT_HB_P_Uplink" function uses HEX Payload as input

"data":"AAAzMgGA" in HEX

Code Block

language	text

# HEX BUFFER : [0x00, 0x00, 0x33, 0x32, 0x01, 0x80]
# In DECIMAL : [0, 0, 51, 50, 1, 128]
