If for whatever reason, you want to rollback to 0.19.216, there is a way:
- Include the file Developer.dat in your SenselApp preferences
- Restart or Launch SenselApp
- Reinstall firmware
If you leave the Developer.dat file in your Preferences folder, you will NOT be notified of any firmware updates. It is recommended that you delete the file from your prefs after you have rolled back, lest you forget.
