1112 +Some models of nodes support sending json format commands separately：**RS485-CB, LDS25-CB, CS01-CB, SDI-12-CB, SW3L-CB, WL03A-CB, PS-CB**

1116 +Downlink command:  **{AT+TDC=900}       **~/~/ The correct format is **{AT Command}**. No extra characters other than valid AT commands can be added within {}.

1122 +
1123 +(% style="color:red" %)**2. Devices designed with downlink commands can utilize different downlink formats (e.g., JSON or HEX) for configuration. However, regardless of the format, the functionality is strictly limited to the downlink command specifications described in the user manual's AT command explanation.**
1124 +
1125 +(% style="color:red" %)**For example, the HEX-format downlink command corresponding to AT+TDC can only be used to configure TDC and cannot be used for queries. There is no HEX-format downlink command equivalent to AT+TDC=? , so querying TDC via downlink is not supported.**
