How to get Activity Logs from Tedee Lock

To send specific commands to get Activity Logs you need to establish PTLS session.

After you have successfully established the PTLS session you need to turn on BLE indications on API commands characteristic. To receive notifications about existing Activity Logs turn on notifications on Notifications.

Note

If Lock has any Activity Logs ready to collect, it will send the notification every 5 seconds.
See Has Logs notification for details.

You are probably familiar with the Activity screen on the mobile app:

Activity Logs in the Mobile App
The information can be obtained from the Lock directly.
Bare in mind, the Lock does NOT store the entire history of its activity. Only the most recent records are stored in the internal flash memory, which allows to store about 100 records.
Once the Mobile App, Bridge or an integrated system receives a package of Activity Logs, the relevant records are removed from the Lock permanetly, making space for new ones.
Use Get Logs command to get Activity Logs records in a binary format called TLV.
An example data received from Lock may look as shown below:
Example raw binary data:
