Issue while recieving null character

Hello guys,

I am using quectel M65 module. I am using Opencpu method with UART & MQTT API’s. Whenever i try to send data which consists of multiple null character it will stop asa null character is detected.
Functions which i use is as mentioned below,
Ql_Mqtt_Recv_Register(mqtt_recv);
ReadSerialPort(port, m_Read_Buffer, sizeof(m_Read_Buffer));

Please help.

Our api detects a null character and uses it as the end. You can try to send an ascii character and convert it in your code, the ascii character is 0x0, or you can try to send a space, the ascii character is 0x20
