B4R Question AT command in HEX

[petr4ppc]

Dear friends, please for advice,

I have module connected to ESP and I send to this module "AT" via serial. The module expect data in HEX format,
is this right solution, please?

Dim bc As ByteConverter
astream.Write(bc.HexFromBytes("AT"))

or this?

astream.Write(bc.HexToBytes("4154"))

I have read :

Thank you

I have read this:
"I think the library () has a bug; it prints the message in binary when the Wisol module expects hex...."...(I know this is not b4r library)
link to messahe about hex

and this is the reason why I want only know, if in B4R is some other way how to send hex than:

Dim bc As ByteConverter
astream.Write(bc.HexFromBytes("AT"))

Thank you

(I hope that it is not dumb question from my side)

...

The AT commands are send in plain Text, only some payloads is send in Hex.
Study examples with Arduino + Wisol BRKWS01.
