Hello, what is behavior of AT+QISEND command? I tried to send data through this command. I’m connected to TCP server successfully but not sure how to use this command properly. Will UC wait until I send 0x1A or length reach? or it will timeout? Manual didn’t say it clearly.
Hi mangmuang，
I found the UGXX module to change the command instructions, I think you can try to refer to, I hope it can help you.
