unable to send more than 1 byte on linux

[8ahmedanwer8]

so i have bluetoothhctl running on my jetson nano which is able to read and write characteristics to and from my arduino's bluetooth module.
problem: i can read several bytes from the arduino but i cannot write more than 1 byte to it. all the bytes after the first one get ignored.

essentially what i have is:
[BT05:/service0023/char0024] write 0x41
the arduino effectively receives this and prints A.

but if i do [BT05:/service0023/char0024] write 0x41 0x42, i should see AB in the arduino but i only just see A

there is a offset option that i might have to use but i don't know how. i came here to this repo to find examples on doing data writes but i find none and i also failed at trying to grasp the source code under gatt.c as well.
fingers crossed!
thanks!
