#
Header prefix, 1 byte
<NoOfDigits>
Number of digits of the following number of data bytes (= 4 in the example), 1 byte
<NoOfDataBytes>
Number of following data bytes in decimal form (= 1024 in the example), 1...9 bytes
<Value>
Data values, each one is a 4-byte floating point value
Example:
#41024<value1><value2>…<value 256>
4: the following number of data bytes has 4 digits
1024: 1024 Bytes of following data; float: 4 Bytes / value => 1024 / 4 = 256 values (128
I and 128 Q values)
<value x>: 4 Byte values, must be interpreted as float

The schema of the result string is as follows:
#(<NoOfDataBytes>)<value1><value2>…<value n>
, with
#
Header prefix, 1 byte
(
1 byte
<NoOfDataBytes>
number of following data bytes (= 1024 in the example), 10 bytes
)
1 byte
<Value>
Data values, each one is a 4-byte floating point value
Example:
#(1677721600)<value 1><value 2> ... <value 419430400>
(1677721600): 1677721600 Bytes of following data; float: 4 Bytes / value ==>
1677721600/ 4 = 419430400 values (200Ms I and 200Ms Q values)
<value x>: 4 Byte values, must be interpreted as float
