Data Logging; Ble Settings - Globalstar ST150 User Manual

9.1.19 Data Logging

Data logging includes logging of GPS track positions, OTA message metadata, and controllable diagnostic logging from the
device's Unified API modules.
9.1.19.1 GPS Position Logging
GPS Position Logging can optionally be disabled to prevent sensitive location data from persisting on the device.
9.1.19.2 OTA Metadata Logging
OTA Metadata Logging logs information about all OTA messages that enter the Transmit Queue (See Transmit Queue
section for logging details).
9.1.19.3 Diagnostic Logging
Diagnostic logging can be used to enable various levels of debug verbosity from each UAPI module, and have those logs
save to flash for retrieval later. This can be very useful for troubleshooting an issue, and being able to review logs after-
the-fact via the Globalstar Mobile App.

9.1.20 BLE Settings

9.1.20.1 Advertising Prefix
The advertised name of the device can have up to 3 proceeding characters customized with the Advertising Prefix setting
9.1.20.2 BLE Power
The transmit BLE power can be adjusted with the BLE Power setting
9.1.20.3 BLE Advertising Interval
The BLE Advertising Interval can be customized. The advertising interval may be disrupted or delayed due to BLE
connections or Smart One Sensor operations (see Smart One Sensor Service Section)
9.1.20.4 BLE Config Service Advertising Enabled
The BLE Config Service Advertising Enabled controls whether or not the config service, Nordic DFU (firmware update)
service, and ASIC DFU services are advertised.
See BLE Configuration Service and Interfaces section for additional details
9.1.20.5 Nordic UART Service (NUS) Enabled
Nordic UART Service is essentially a UART over BLE, and can be optionally enabled or disabled. See BLE Configuration
Service and Interfaces section for additional details
9.1.20.6 Smart One Sensor Service Settings
Smart One Sensor Service is a BLE service the ST150M offers where up to 10 sensor nodes may advertise data to be sent
over-the-air when data is available and needs to send. The ST150M will switch from peripheral mode to central mode at
the Sensor Service Scan Interval below, and look for any advertising sensor nodes.
Up to 10 sensor nodes can work in conjunction with a single ST150M.
When a sensor advertisement is discovered, the sensor's data is captured and sent as a Type 59 or Type 63 Sensor OTA
Message (See Messages Section), and the sensor becomes whitelisted for a minimum of several seconds.
ECDSA is used in combination with a configurable AES public key to provide authentication of messages. Additionally, the
device's ESN or UID can be used to authenticate sensor nodes meant only for the intended ST150M.
