However, regardless of the format, the functionality is strictly limited to the downlink command specifications described in the user manual's AT command explanation.**

1177 +(% 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.**
