This is not a nordic related "issue", or an "issue" at all, really.

If you know that the message will always end with "$", then you need to check the three bytes before that. I suggest you look at the ble_app_uart example for how to store the incoming data. You will get an event for each incoming byte, but this example checks if the last byte is a linefeed, or if the buffer is full. At that point, it will send the packet over BLE. Perhaps you can reuse some of the same logic to do what you want to do.

Best regards,

so far i have only managed to get the write to work, but i have a read function i just need some help with how to do the event handler part

but yes as you said if i read 123$ i would have a function called 123

if i read 456$ then i have a function called 456

So how far did you come?

Do you see the input bytes?

Do I understand correctly if this is the case?

If you receive the string "123" you should call one function, but if you receive the string "456" you should do another task?

What is it that you are stuck on? How to interpret the incoming string?
