MQTT: SubTopic received, while receiving command echo

Question

Hello, I have the following problem: I am subscribed to “subtopic/test” (which periodically sends "subtopic message") UART Receive Buffer: subtopic/test -> subtopic message
 I periodically publish this message "HelloWorld!" (echo enabled) UART Receive Buffer: AT+MQTTPUB="HelloWorld!"


OK
 Occasionally, i receive the subtopic, while receiving the echo or repsonse. UART Receive Buffer: AT+MQTTPUB="HelloWsubtopic/test -> subtopic message
orld!"


OK
 Is this behaviour intentional? It makes parsing much more difficult! Best regards, srcnuzn

Hello. Sorry for the late reply. How about publishing a message if there is no received data(subscribe message) after reading the MCU’s buffer first? Please refer to it. Thanks. Best regards.
