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.**

1219 +
1220 +
1221 +=== Why can't the password access AT command after upgrade(-NB)? ===
1222 +
1223 +
1224 +Because the new version of -NB firmware has updated the factory reset function, users can choose to restore all parameters to factory Settings, or keep the password to restore the rest of the parameters to factory Settings.
1225 +
1226 +This update changes the password address of the firmware, so the password will be invalid after the customer upgrades from the old version of firmware (without FDR1 function) to the new version of firmware (with FDR1 function).
1227 +
1228 +Two different restore factory Settings configurations.
