Hi,
I tried with smartphones Samsung S5 with Android 6 and Huawei Honor 10 with Android 9
I had license B4A 8.8 but I back to version B4A 6.80 due problem with Sleep.
I bought B4A 9.3 yesterday but problem with Sleep is still (as before - freeze my app, printing OK)
I have to use Sleep due printing via Bluetooth file print.txt (size is 6-8 kB; in mybufx).
It prints without Sleep only first cca 1kB of file (disconnecting is faster than printing all buffer; not freeze my app).
Thanks for any solution with sub Sleep or with "Wait for".
Please link to B4A version 6.80. I back to old version B4A.

B4X:
In Process_Globals: Dim mybufx() As Byte
...
mybufx= File.ReadString(dird, "print.txt").GetBytes("windows-1250")
...
Sub Serial1_Connected (Success As Boolean)
If Success Then
Dim os1 As OutputStream
os1=Serial1.OutputStream
os1.WriteBytes(mybufx, 0, mybufx.Length)
os1.Flush
Sleep(2 * mybufx.Length + 4000) 'freeze; too Sleep(2000)
Serial1.Disconnect
Else
MsgBox("Error BT...","")
Serial1.Disconnect
End If
End SubThanks for any solution with sub Sleep or with "Wait for".
