Read() operation

[RahulMvr2824]

I'm performing a device.read() operation to fetch data from the bluetooth module. As I understood this operation works like First in First Out which means the message that comes first will be read first. But I had a use case where I want Last in First out method. Is there any way for that process using device.read().

Thanks in Advance!!

With the standard functionality no, there is not. With that said, you have a number of options:

1. You can create your own ConnectionImpl which extends from the standard DelimitedStringConnectionImpl and overwrites the read method to return the last message instead of the first message. You then need to overwride the standard native module creation. I believe there is a documentation page on how to do this.
2. If you think this is standard enough functionality, you can introduce a connection parameter for the DelimitedStringConnectionImpl that when set would return the buffer in a LIFO (instead of FIFO) order, I'd accept a PR for this.

These are the only options at this point in time.
