1) most devices it will return `shake 00`
-> shake
<- shake 00

2) here is two cases
-> net
# my case
<- net cloud
# another cases
<- net unprov

3) dn number could be depended by devices
-> get_dn
# my case
<- get_dn 100801210820000007 
# another case of this debug
<- get_dn 3

4) pk number could be also depended by devices
-> get_pk
# my case
<- get_pk a1hiSOeUajy
# another case of this debug
<- get_pk 3

5) timestamp could be current time
-> timestamp 1629831426
<- timestamp 0

6) version value is related by device
-> version
# my case
<- version 0014
# another case of this log
<- version 0006

7) initialized getting properties. this command only callable after handshake (~ after sending `get_pk` or after sending `version`)
-> servers getProp 1 3 7 8 9 16 17 18 19 21 22 23 24 31
# i'm not sure but this first return could be always same
<- servers 0 
# second / third return could be depended by current device conditions
# for example `ControlMode` was `1` in this log
<- props ControlMode 2 ChildLockSwitch 0 runState 0 handrail 0 MaxW 6.0 Max 12.0 StartSpeed 2.0 VelocitySensitivity 2 PanelDisplay 7
<- props ConSpMode 0 initial 4 mcu_version "0001" unit 0

8) now can send command
-> props ControlMode 1
# then we can feed the response of status of the device.
<-  ...

# with original key
> e64 props netled 0 ControlMode 1
