B4J Question Asyncstream - Send string and bytes combined

Are you sending the data between two Android devices?

No this is a B4J app that send data to an electronic device via jSerial. Since it's an AT commands communication, I have to use asyncstreamtext to make sure the packet is complete when the event is riased in the b4j app.

You can convert the long to 4 bytes with ByteConverter.LongsToBytes (Array As Long(DateTime.Now)).
Send the string and then send the bytes array. Or combine both of them to a larger array of bytes (ByteConverter.ArrayCopy will help).

Thank you Erel,
I've made some tries but I'm still unable to do what I need. To be clearer, my system needs the time in second since 1 jan 1970 in an 4 bytes format. So I have to divide DateTime.Now by 1000. This is not a problem.

But when I convert it to a byte array with ByteConverter.LongsToBytes like you suggest, I receive 8 bytes (see the attach screenshot). I'm only interested by the last 4 ones. I've try to send them with this line but I did not receive anything. AsyncstreamText expect a string as input.

1. Use IntsToBytes instead of LongsToBytes.
2. Make astreams in AsyncStreamsText class public and write the bytes directly:
