I am trying to get this new node working on data coming from a bluetooth pressure sensor. I cant seem to get at the nested data correctly.

Here is the data for the first value.

I stringified the bluetooth output to this, and still cant seem to get it retrieved.

I should mention that the payload has 2 items of interest.

1. Characteristics key
2. Data

The sensor returns all of the following.

Hi, when you capture a debug output - please do the following...

1. Press the "Copy Value" button that appears under your mouse pointer when you hover over the message in the debug sidebar (it copies it correctly - what you pasted is pretty much unusable)
2. Be sure to paste it as a code block (surrounded by 3 backticks on new lines)

* * *

OK, so by the looks of it, your `buffer` from the BLE node is in `msg.payload["2a29"].characteristics` but you have the input property of the buffer parser set to read `msg.payload` - hence the error.  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/4/4/44d4cdc514e930e8b1ca8186c903228edb16a052.png)

So, I have put together a demo using the buffer values I found in your post `[84,114,97,110,115,100,117,99,101,114,115,32,68,105,114,101,99,116,32,76,76,67]` and connected that to the buffer parser (to fake your BLE node (I dont have BLE or your device so I have to fabricate the data))

This is the result ...

^ note how all values are essentially starting from the 1st byte? ...

This is because yo havent set any offsets...

I stepped back and can't seem to get the data to represent the temperature.  
Here is the payload and the configuration. The vendor says its a 32 Float BE value and I keep getting the error.

RangeError: The value of "offset" is out of range. It must be \>= 0 and \<= 0. Received 4

This is the message passed into it.

You did neither of these ☹ that makes it is very difficult for me to help you as I cant easily copy what you pasted!

Onto your issue...

... your input data is only 4 bytes long & you are trying to read 3 floats from it.

More, so, that data [0x41,0xcb,0x30,0x0] looks suspiciously like a string.
