Yes, thats right. No I cant split it, because I cant change the transmission from the sensor.

Oh thanks for information. Now I know it :)

You want to receive 26 bytes, is that it? can't you send in two packets per transmission?

PS- when you edit your question/answer try to check the box "minor edit", because if you don't do it I receive one email per edit ;)

The sensor will send 26 Bytes for one sequence. But I cant read all 26 Bytes, because:

BLE_NUS_MAX_DATA_LEN (GATT_MTU_SIZE_DEFAULT - 3)

GATT_MTU_SIZE_DEFAULT 23

Only the default MTU size of 23 is currently supported.

I just dont want to believe, that I can read only 20 Bytes in one sequence??

I'm not sure how you getting the 5 bytes. You are getting 5 Bytes because you are sending 5 chars: 2 times "\n", 2 times "\r" and one "C".

And you are getting the "C" on the middle one. You receive the LSB first, so from your image you get on the 3 Byte "11000010" that you need to reverse the order to "01000011" which is 0x43 and "C".

The others values are 0x0D for the carriage return and 0x0A for the line feed.
