Is battery level available via BLE ?

[DDHF22]

According to the manual the battery level can be seen in the app/cloud.
Is that value available via BLE as well ?

Seems raw data contains more data than forwarded by the code
(
1, # byte version
57, # byte humidity2
109, # byte not documented ???
2, # byte not documented ???
120, # short st-radon
101, # short lt-radon
2845, # short temp100
50832, # short pressure*50
486, # short CO2
65535, # short VOC
1, # short not documented ???
65535 # short not documented ???
)

After applying fresh batteries I see

(1, 45, 107, 0, 126, 106, 2923, 51208, 715, 122, 0, 1078)

and it seems the two undocumented 0'es are related to the proximity sensor where the first apparently is 1 if the LED have been read recently and that last 0 indicates the number of seconds the LED has been on the last 10-15min.

I hope the last undocumented (1078 in above) is a battery indicator but is does not continuously declining which I would expect from a discharge. Instead it is modulating in the range 990-1110 ?
