B4R Question memory limit b4r/ESP?

[MbedAndroid]

i'm trying to decrypt the p1 output from the electricity meter.
With debugging the program crashes after a few testlines. The amount of lines seems to be the problem.
I thought the ESP has enough memory to run a simple program
example:

Private Sub Timer1_Tick
'   Dim s()="1-0:1.8.1(003808.351*kWh)" As Byte
'   Dim buffer As String=JoinStrings(Array As String(wifi.LocalIp ,",","P1",",",bc.HexFromBytes(MacAddress),",",s))
'   usocket.BeginPacket(ip, port)
'   usocket.Write(buffer)
'   usocket.SendPacket
   Dim s()="1-0:1.8.1(003808.351*kWh)" As Byte
   Log(Parsing(s,"1-0:1.8.1"))
   s="1-0:1.8.2(002948.827*kWh)"
   Log(Parsing(s,"1-0:1.8.2"))
   s="1-0:2.8.1(001285.951*kWh)"
   Log(Parsing(s,"1-0:2.8.1"))
   s="1-0:2.8.2(002876.514*kWh)"
   Log(Parsing(s,"1-0:2.8.2"))
   s="0-0:1.0.0(101209113020W)"
   Log(Parsing(s,"0-0:1.0.0"))
   s="1-0:1.7.0(01.193*kW)"
   Log(Parsing(s,"1-0:1.7.0"))
   s="1-0:2.7.0(00.010*kW)"
   Log(Parsing(s,"1-0:2.7.0"))
   Dim s()="0-1:24.2.1(101209112500W)(12785.123*m3)" As Byte
   Log(Parsing(s,"0-1:24.2.1"))
   Dim s()="0:96.14.0(0002)" As Byte
   Log(Parsing(s,"0:96.14.0"))
   Log("packed send")

End Sub

It's independed what line i exclude, simply too much lines will crash the program
with 6 lines it runs fine, more:crash
also i tried to dim each static line, makes no difference

edit increased the stackbuffersize to 400, helps a lot

i'm trying to decrypt the p1 output from the electricity meter.

Private Sub Timer1_Tick
 Dim s()="1-0:1.8.1(003808.351*kWh)" As Byte
 ......
End Sub

I think your declaration of your byte array is wrong, it must be

Private Sub Timer1_Tick
 Dim s() As Byte = "1-0:1.8.1(003808.351*kWh)"
 ......
End Sub

There's a message while compiling how much of the memory is used. I use heavy RSA & AES methods and only 15% of the memory is used on a ESP32.

yes i know, that's was ok. I increased stackbuffersize to 900 , solves the problem

When you allocate lot of resources in subs, they are released only on sub exit. So stackbuffersize must be sized to support suck activities.
Embedding subs(with lot of allocations) is terrific for memory.
