V7 EXTERNAL ANTENNA RTLS MODULE USER MANUAL 3.2.1. Reset The module can be reset externally by driving the nRST_i pin low for at least 0.5us. nRST_i is internally pulled up and no external pull-up is necessary. During bootup, the module will drive nRST_o low for at least 10ms. Once the module is operational, the nRST_o will be tri-stated. Note that nRST_o is only asserted after nRST_i is de-asserted. 3.2.2.
V7 EXTERNAL ANTENNA RTLS MODULE USER MANUAL 3.4. RF Transceiver The module has two complete radios, the UWB and the Bluetooth® radio. The module contains a UWB radio operating in the unlicensed UWB band. The transmitted signal bandwidth is 500 MHz or greater. The unit is calibrated such that the maximum radiated spectrum density does not exceed -41 dBm/MHz and is fully compliant to the spectrum mask defined in FCC part 15.

V7 EXTERNAL ANTENNA RTLS MODULE USER MANUAL The RTLS module supports communication over UART interfaces. 4.2.1. UART Interface The UART is the full duplex bi-directional interface between the module and the external host device. The following is the physical configuration of the UART: Baud rate: 115200. No hardware flow control. 8N1 byte format. 4.2.1.1. UART Modes of Operation The module’s UART has two modes of operation, command and binary.
V7 EXTERNAL ANTENNA RTLS MODULE Name Type Values USER MANUAL Description z int32 Position Z in mm. sl uint16 Area ID fom uint8 er uint32 op string ts uint32 50-255 Figure of merit—confidence level of the position estimate. A smaller value is better. Note: Not available for 1D, 0D and PD positioning mode. 0D mode - distance to 0D anchor in mm. 1D mode – distance to the line connecting anchor pair(mm). Note: Only available in 0D and 1D modes.
V7 EXTERNAL ANTENNA RTLS MODULE Name Type md uint8 USER MANUAL Description 0 - no motion detected / 1 - motion detected TABLE 10 CONTENT FIELDS OF THE IMU MESSAGE. The following is an example of the IMU raw readings: #IMU ax=ddddd ay=ddddd az=ddddd rx=bbbbb ry=bbbbb rz=bbbb ts=45376 md=1 4.2.2.3. #ALM – Alarm Alarm messages start with the preamble #ALM and have the following content fields: Name Type Values Description t string SA|CA Alarm type.
V7 EXTERNAL ANTENNA RTLS MODULE USER MANUAL Note: When the alarm message is sent, the nALM_o is also driven low if special purpose nALM_o is configured using CFG command. 4.2.2.4. #MSG – Server message ASCII messages received from the server are issued from the module as #MSG messages. This message type is indicated with the preamble #MSG, followed by the actual ASCII strings of the message. The preamble and the body of the server message is separated by a space.
V7 EXTERNAL ANTENNA RTLS MODULE Name Type USER MANUAL Description sn string MAC address of the module. hw string Hardware revision of the module. cbid string Carrier board ID. fw string Firmware version. TABLE 13 VERSION MESSAGE CONTENT FIELDS The following is an example of the #VER message: #VER sn=E4956EAE01BB hw=7.0 cbid=3E61 fw=5.7.1 The module will print version messages at bootup automatically if the “Keep CMD on” flag is set. 4.2.3.
V7 EXTERNAL ANTENNA RTLS MODULE USER MANUAL CFG config_word where config_word is a 32bit hexadecimal value (reset value is 0xA0000000). The ‘0x’ prefix is not required. If the command is sent without the value field, it is treated as a read command and the module will output the configuration value.
V7 EXTERNAL ANTENNA RTLS MODULE USER MANUAL Note: The local pos output at tag UART (CFG OUT en=P) may not be matched with the pos updates sent to server when AF (Advance Filtering) is enabled on tag. Please refer to 3.2.4.4 CFG IMU for more details. When AF is enabled, the pos update could be sent from AF with IMU data. The local pos output (CFG OUT en=P) could be mismatched with the pos data sent to server.
