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".

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.

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

The UWB module features a BLE chip, nRF52833, which serves as the main controller for the entire module. The UWB chip does not include an MCU and requires control through the nRF52833. Additionally, the module is equipped with an accelerometer sensor, as well as antennas for both BLE and UWB functionalities.

We use SEGGER Embedded Studio for ARM. It is recommended to use version 5.40C; higher versions may encounter issues.

NXP, NewRf, DecaWave, and Chixchip have all released UWB chips with integrated MCUs. There have been customer feedback regarding the performance stability of NewRf's chips. Chixchip claims to have an ultra-low power UWB chip.

Not all mobile phones can support acting as BLE slaves. When an iPhone acts as a slave, its MAC address keeps changing.
