Using LIST to hold input - getting screwed

PhilMonfie · October 26, 2023, 3:50pm

I'm trying to create a small section of code to illustrate the problem, but basically;

I'm receiving data over BLE - which works fine. Input blocks are 20 bytes each and coming in through the BLE Callback function, and I'm adding these to a LIST using AddLast. I can Serial print this data and it's all fine. There is a 'Start' block and an 'End' block so I know when it's all in.

The main Loop of code is processing these blocks using getValue(0) each time around the loop - processing then doing a removeFirst.

Their are 2 problems;
All of the input comes in very quickly - just over 150 entries of 20bytes added to the list. But when I do the getValue - the data is not what I put in?

The second issue is that after processing 4 or 5 entries from the list - it starts to process the 'End' block - which should have been put in LAST.... and continues to process this after every other entry.

Totally confused.

As I said I'll try to create some code to illustrate, but the whole sketch is quite big and may confuse things.

Yes, please. Until you have some code that shows the problem, all that can be offered are vague generalities.

It's all relative. If you can't make a minimal sketch illustrate your problem, consider posting the entire ~~mess~~ thing.

Output on Serial Monitor

(I've removed the data in and processed numbered 0 - 4, just preamble)

Line 5 says 'SIGSTART' . Line 160 received has 'SIGEND'

Line 161 received says 'VIND2'...you can then see that this data gets processed over and over from line 60 to process onwards every couple of lines.

BLE init started
BLE init done
Waiting a client connection to notify...
Done setup
Device Connected

The code is posted - any ideas?

gcjr · October 27, 2023, 11:30am

doing a lot of prints while trying to read data may be delaying the read process. once the serial output buffer gets filled, serial prints block

rather than print all the data, perhaps just print a single char for the start and end markers and a count every 20 value

alto777 · October 27, 2023, 11:58am

I got nothing.

How much experimentation or testing did you do of just the List object?

If I attack this, it will start back at List examples code, and proceed to a very much more cut down sketch that aims to stress the list mechanism in the same way as your blue tooth code.

Also, I don't have on the top,of my head, but isn't there a way to detect if you have allowed buffers to overrun whilst being busy printing or whatever?

Also what mean these lines?

+1
Cut the code back to bare-bones and work up, only adding complexity once the previous tests work perfectly.

@PhilMonfie, you didn't tell us the processor type. But, I'm guessing ESP32 given the BLE code. So, on an ESP32, I'm curious about this:

Why use a non-standard List type when the STL containers are available to you?

#include <List>

std::list<std::string> Rcvdata;

The STL is thoroughly tested and debugged. And, as the name implies, is Standard.

gcjr · October 27, 2023, 12:51pm

i think the focus should be on verifying the transmitted data correctly without and post processing. send a sequential set of values and verify the correct number have been received when the end marker is received and/or that the end marker is received after the correct # of values

if there's a problem, verify the values of the data when received

with those tests in place, deal with capturing the data without error. perhaps just copy it into a char buffer.

and then deal with post processing without error

PhilMonfie · October 27, 2023, 2:28pm

Thanks for all of your help guys, and suggestions. This was driving me nuts so I've re coded, processing the input bytes as they are received in the callback function, and moving them into a 2 dimensional structure - which is then displayed from the main loop. This works fine.

Not sure whether I was using LIST wrong or whether there is a problem - but I've ditched it for now.

Thank again for your interest and suggestions.
