I'm using (right now) an Argon running OS4.2.0. I'm using it in the BLE Central Role and have connected to a peripheral. I'm polling it for data. The peripheral reports it will send 297 bytes of data via the UUID characteristic. This of course causes packet fragmentation. I then read the peripheral…

Sorry for confusion. No, these aren't related. This one is real. I have verified it on several OS versions (including 5.6.0, 4.2.0, 4.0.1 and 4.0.2). It drops the first byte on the second packet. Easy to reproduce.

Hi @tnilsen I read through your code and while I don't directly see problem, I do see that you are doing a lot of String operations with substrings based on the found indices of various characters. so my question is: Can you reproduce this without all the String work and just dump the raw data to …

Thanks for looking at this. I get what you’re saying - potential memory leaks. The code I placed on GitHub was made much after I found the this issue. I spent time first just getting the BLE exchanges going and that’s when I discovered a byte was being dropped. Fortunately the byte doesn’t contain r…
