Bluetooth logger windows

Paired deviced are usually detected even when they are not active, so this option allows you to hide them. What can you do with BluetoothLogView? If you have neighbors or family members that use a cellular phone with Bluetooth turned on, you can easily find out when they come home and when they leave. A new log line will be added every time that their cellular phone arrives to your area and every time that their cellular phone left your area.

In order to start using it, simply plug the Bluetooth dongle and then run the executable file - BluetoothLogView. The description is saved in the. In order to set the description, simply double-click the log line and in the Properties window, type the desired description.

The health and well-being of our customers, suppliers, employees, and the surrounding community is of the utmost importance to us, so we are taking the necessary precautions to keep everyone safe. Connection interval, slave latency and other settings are sent upon during a connection, and they can tell you a lot about what the devices agree to. For example, an Android or iOS device that has to communicate with multiple devices may need to use a longer connection interval to be able to service all devices.

This can cause all kind of issues from low throughput to disconnect. The central device constantly updates its channel table depending on the environment. How this is done is proprietary to each BLE chipset vendor, but usually relies on measuring packet loss, RSSI levels or a combination of both. One of the first things we do when a customer sends us a capture or a device to analyze is to look at the environment. A lot of interference can be a problem and can explain lost packets, disconnections, low throughput, etc.

Although you can use a spectrum analyzer device that looks at the full 2. You can tell whether a packet had been retransmitted by looking at the change in the serial. The connection interval depends on both devices in the connection. For example, Android allows up to 7. With a BLE sniffer you can see exactly how many packets are being sent in each connection interval, who is sending it, and how many bytes are being sent. If your throughput is too low, you should be able to see why looking at the data exchange, the connection parameters the devices agree to, etc.

It will also let you find who is at fault. Although not always used in BLE products, security, along with paring and bonding are important to understand. Several sniffers support sniffing data even if encrypted. In the case of the Nordic BLE sniffer it supports:. Most BLE devices talk to a smartphone on the other end. Both iOS and Android include the ability to capture the data and the events.

The developers of the Bluetooth stacks in both companies use this ability to find bugs in their own stacks, and you should use it too. In iOS, enabling Bluetooth logging requires installing a special profile in the device. In this case, a processor runs both the user application and the BLE stack. Debugging the firmware can be more difficult than other embedded systems because the BLE stack needs to meet certain timing constraints.

The other device could end up assuming that the board being debugged disconnected clearly not the case. This is one of the most critical things to understand about using a debugger. We have several approaches that are used in real-time embedded systems. All these approaches have tradeoffs. The right approach is to find something that is fast and provides the information you need to debug the issues.

This is a very simple and non-intrusive approach. Basically you set up a way to toggle a certain GPIO in your board when an event happens. Because changing the GPIO state is very quick 1us or less in most cases , the effect on the system timing is minimal. Using an LED is similar but it is much slower and provides less information.

Printfs are common when debugging on computers. But the problem is that most UART modules have no buffering capability.

This takes time. Interrupt implementation are much better. With a standard baudrate of , it can take several milliseconds to send the data across. This may or may not cause an issue.

Like any tool, use it judiciously. The advantage here is that this is very fast. Inserting data in the buffer takes a few CPU cycles, depending on the amount of data. But this can store the process through which the system is going. Implementing this can be as simple as an array of numbers that show the state, but more likely it can be more complex. This complexity is a double edged sword which can provide tremendous amount of information or be complicated to implement.
