This BLE app has several features which I will highlight in a brief overview.
1. The BLE app upon entry will scan for BLE advertisement packets, and report them on the screen. The Channel knob can be used to select which advertisement channel to listen on.
2. Once found the user can then select an individual MAC Addresses entry to pull up a more detailed view of the captured data packet.
3. The Sort Knob will sort the list of MAC indices by either Ascending MAC Address, dB, or by most recently updated entry.
1. The BLE app upon entry will scan for BLE advertisement packets, and report them on the screen. The **Channel** knob can be used to select which advertisement channel to listen on. There is an Auto feature which will switch channels upon receiving a new packet. (Randomized from 37-39).
2. Once found the user can then select an individual MAC Address entry to pull up a more detailed view of the captured data packet.
3. The **Sort Knob** will sort the list of MAC indices by either Ascending MAC Address, dB, or by most recently updated entry.
4. The **Filter** button allows the user to filter based on the hex data of each packet. It also allows for filtering based on the ASCII name of the device (if found). More on that below.
5. The **Name** toggle allows the user to toggle off and on name display, if there is a name associated with the device. Not all devices have a name string. This name string is being parse from the Shortened and Complete Local Name packet type. See BLE Spec for information on packet types.
6. The **Clear **button allows the user to clear entries as they fill up the screen.
7. The **Export CSV** file allows the user to export the current list of packet entries into a csv style file. Upon resaving the file, the file will update the existing entries with new data, as well as append new entries to the existing file.
8. The **Tx** button allows the user to switch to the BLE Tx app. See BLETX for more information.
Below short example on using the BLE Rx App.
