B4R Question Bad Results from ByteConverter

[thali]

I get strange results from ByteConverter:

what is the problem?

Hi, are you using the b4a lib or RandomAccessFile lib ?

 

[thali]

I use the rRandomAccessFile lib V1.91 from B4R.

 

[Justcooldev]

maybe this could be the solution...

 

[thali]

unfortunately not:
Dim floatStr As String = "12.34"
also won't work. (I have to process ascii characters from stream of bytes)

What exactly are you trying to do? I think assigning a string to a byte array is where you are going wrong, but I have not used B4R so I don't know if that is OK or not. It isn't in the other B4X languages.

Have you tried

Dim floatStr() As Byte = "12.34".GetBytes

(I can't test it as I have just discovered I have no com ports on my laptop so can't run B4R lol)

Thank you all for the hints!
I also cleaned the project but the output still was the same.
Running the test code on an other board(M5Stack-Core) gives the same result.
In my project I have to parse NMEA strings comming from a GPS. According examples on this forum the code should be like this:
Code:
Dim floatStr() As Byte = "12.34"
Log("float$=",floatStr)
Log("isNrF$? ", IsNumber(floatStr))
Dim f As Float = bc.StringFromBytes(floatStr)
Log("f=",f)

Log("+++++++++++++++++++++++++++++++")

Dim intStr As String = "123"
Log("int$=",intStr)
Log("isNrI$? ", IsNumber(intStr))
Dim i As Int = bc.StringFromBytes(intStr)
Log("i=",i)

Output:
ESP-ROM:esp32c3-api1-20210207
AppStart
float$=12.34
isNrF$? 1
f=12.3400
+++++++++++++++++++++++++++++++
int$=123
isNrI$? 1
i=123

Try this code

    Dim floatStr As String = "12.34"
    Log("float$=",floatStr)
    Log("isNrF$? ", IsNumber(floatStr))
    Dim bc As ByteConverter
    Dim f As Float = bc.StringFromBytes(floatStr)
    Log("f=",f)
    Log("+++++++++++++++++++++++++++++++")
    Dim intStr As String = "123"
    Log("int$=",intStr)
    Log("isNrI$? ", IsNumber(intStr))
    Dim i As Int = bc.StringFromBytes(intStr)
    Log("i=",i)
