Hello!
Im trying to transfer from RPI4 to Rock PI 4 with my project and have got a problem within this porting
Now Ive already installed Node-RED version v3.0.2, Node.js version v14.20.1 on Linux 4.4.154-116-rockchip-g86a614bv15b3 arm64 LE
I have got rock pi 4a v1.47
In Rock my node-red project hasnt started yet
I supposed what the problem in drivers
So I started trying to test transfer data via terminal first
So in my attempts in transfering and receiving data via terminal using USB-RS485 dongle I have the following results:
- I can send string and receive that too
- When I send hex data I receive unrecognized data. In RPI this test successfully passed
And at this point I stopped unfirtunally
Please help
