Same as with WiFi devices, Bluetooth (BT) data loggers need to connect to the network via a point of access so they can send data to servers, the cloud, apps, etc. They do this by communicating with a BT gateway (which in a way is like an AP) or a mobile device (phones, tablets, etc.). So, how can NetAlly tools help troubleshoot or validate BT data logger communications?
- Validate data logger configuration by providing visibility into advertisement flags and data. For example, data loggers can use Eddystone or iBeacon information to specify their location in a building, and thus help you keep track of temperature and humidity in specific areas throughout a site.
- Measure data logger signal coverage. Different from WiFi APs, BT gateways do not transmit data, they can only receive data. This means you need to validate (survey) data logger coverage instead of gateway coverage. The gateways can normally provide data logger signal strength information, but what happens when a gateway loses visibility of a specific data logger? That is when the NetAlly wireless handheld testers come in! A technician can take a NetAlly wireless analyzer to the field and measure the signal from the data logger. Is it still transmitting? Did someone put a big metal box in front of it and its signal got attenuated? Etc.

In conclusion, BT data logger troubleshooting and validation, doesn’t have to be difficult. NetAlly wireless analyzers make it easy to troubleshoot problems with data loggers sending inaccurate information because they were not configured correctly, or intermittent communication problems caused by low signal strengths.
