Dear Sir:
I have a bluetooth project,and it has two function.the first is get BT device's info and another one is download config file from web service,the first one jsut a 4 byte command and then i can get response from BT device info,but the second command is a big size command about 10507 bytes, when i send the command,the BT device can't get any response,When i told the problem to our BT device engineer and check the command is correct,we found the problem may cause of the BT bandwidth.I wanna prove it,so i used the frist command to test as followed
Above is the code work fine,I can get the BT info,Next i wanna separate the command to test
i get the BT device response:timeout
where am i wrong?or is there have another way the separate the command?

B4X:
Dim TriggerPayment() As Byte = Array As Byte(0x00, 0x02, 0xF2, 0xF2)
AStream.Write(TriggerPayment)
Above is the code work fine,I can get the BT info,Next i wanna separate the command to test
B4X:
Dim TriggerPayment() As Byte=Array As Byte(0x00, 0x02, 0xF2, 0xF2)
Dim BufferSizeMax As Int = 2
Dim BufferSize As Int
For i = 0 To TriggerPayment.Length -1 Step BufferSizeMax
BufferSize = TriggerPayment.Length - 1
If (i + BufferSizeMax) > (TriggerPayment.Length - 1) Then
BufferSize = TriggerPayment.Length Mod BufferSizeMax
Else
BufferSize = BufferSizeMax
End If
Log(i & ":" & BufferSize)
AStream.Write2(TriggerPayment, i, BufferSize)
Next
i get the BT device response:timeout
where am i wrong?or is there have another way the separate the command?
