I'm trying to read level data from a Behringer XR18 mixer
program for ESp8266 on Arduino, WiFI
how to send a command to the mixer to get data?
how to decipher the answer in order to get the data for each channel?
here is a piece of description for XR18
Meter subscriptions
meter subscriptions are used to request a set of meter values,e.g.:
/meters ,si “/meters/0” 8 (meterID ,oscvalues )
Binary OSC message:
2f 6d 65 74 65 72 73 00 2c 73 69 00 2f 6d 65 74 ; /meters.,si./met
65 72 73 2f 30 00 00 00 00 00 00 08 ; ers/0.......
… returns 8 channel meters (pre-fader l/r, gate and comp gain reduction, post-fader l/r
meters, gate key, comp key) of channel 9:
List of Meter IDs:
/meters/0
CHANNEL:
8 channel meters (pre-fader l/r, gate and comp gain reduction, post-fader l/r meters, gate
key, comp key)
-> returns one integer size value and 8 short signed integer values (16 bit) as single binary

/meters/1
ALL CHANNELS:
16 mono + 5x2 fx/aux + 6 bus + 4 fx send (all pre) + 2 st (post) + 2 monitor
-> returns one integer size value and 40 short signed integer values (16 bit) as single binary
blob
/meters/2
ALL INPUTS:
16 mic, 2 aux, 18 usb
-> returns one integer size value and 36 short signed integer values (16 bit) as single binary
blob
/meters/3
FX METERS:
4 x (2 x input, 10 x fx return, 2 x output)
-> returns one integer size value and 56 short signed integer values (16 bit) as single binary
blob
/meters/4
RTA100:
100 bins RTA
-> returns one integer size value and 100 short signed integer values (16 bit) as single binary
blob
/meters/5
ALL OUTPUTS:
6 aux, lr, 16 p16, 18 usb, headphones
-> returns one integer size value and 44 short signed integer values (16 bit) as single binary
blob
/meters/6
ALL DYN:
16 gate, 16 dyn(ch), 6 dyn(bus), dyn(lr)
-> returns one integer size value and 39 short signed integer values (16 bit) as single binary
