Forgive us! We messed up a bit in the previous software release — 3.35. The bug is expressed in that the mobile application cannot receive data from the device when it is turned on again. This issue has been fixed in version 3.36. You can also restore data transfer by re-enabling data transfer via BLE in the device settings (OPTIONS — BLE -> APP), although you have to do this every time you need to connect a mobile application. Therefore, it is better to upgrade!
