Frequently Asked IoT Module Questions

What is the maximum total length for AT commands?

Time2023-08-07

Username and password length allowable range: [1, 1024] bytes.

When the module is set as an MQTT client, what is the allowable length range for the client ID and password?

Time2023-08-07

Username and password length allowable range: [1, 1024] bytes.

When using the AT firmware and the module is configured as an MQTT client, what are the available QoS options for the Last Will and Testament (LWT)?

Time2023-08-07

Supported values: 0, 1, 2; Default is 0.

When using the AT firmware and the module is configured as an MQTT client, what is the maximum length for the MQTT broker domain name and the maximum port number?

Time2023-08-07

Maximum domain name length: 128 bytes; Maximum port: 32 bytes.

When using the HID functionality and using the AT+BLENAME command to modify the device name, why does the broadcasted name still remain as the default?

Time2023-08-07

The issue with the ineffective AT+BLENAME setting is due to the Bluetooth LE HID command not being compatible with GATT/GAP commands simultaneously. If HID renaming is required, use the AT+BLEHIDNAME command to set the device name; for example, AT+BLEHIDNAME="MS11SF11".

Does GNSS module support ADR?

Time2023-08-14

ADR stands for Automotive Dead Reckoning, which is inertial navigation for vehicles. Currently, our module only supports UDR (Unconstrained Dead Reckoning), which refers to inertial navigation without constraints.

What UWB module functionalities can we currently customize?

Time2023-08-14

Currently, with UWB, we can only achieve distance measurement. If UWB distance measurement is used in applications, we can provide firmware customization.
