How to calculate checksums from serial data

How to calculate checksums from serial data - vb.net

I have an application written in vb.net which listen to a serial port, the following is the bytes I received:
B3 01 33 00 00 00 01
B0 01 33 00 00 00 02
B1 01 33 00 00 00 03
B6 01 33 00 00 00 04
B7 01 33 00 00 00 05
81 01 33 00 00 01 32
B0 01 33 00 00 02 00
82 01 33 00 00 02 32
B1 01 33 00 00 03 00
83 01 33 00 00 03 32
B6 01 33 00 00 04 00
84 01 33 00 00 04 32
B7 01 33 00 00 05 00
I want to get the correct calculation or process. How to get the first byte?
Which is B3, B0, B1 and so on.

Raw H265: How to tell which bytes are equal to a whole video frame?

I have a raw H265 video file. I want to understand the exact mechanism to tell which bytes are separating every frame and another, in order to send it over the network to be decoded by a remote app.
I have a faint understanding about NAL units, and I tried to grasp what CSD-0, CSD-1, SPS, VPS, PPS are, but I couldn't put two and two together. I tried dividing the entire byte sequence of the file (they call it a bitstream I think) to chunks, on every incidence of a NAL header (00 00 00 01) but the result are just undecodable bytearrays, none of them corresponds to an actual frame.
So, what am I missing ? I welcome any code in any programming language as I have a broad understanding of a variety of languages, what matters here is the algorithm that is used to detect frames in a byte sequence of a raw H265 video file.
This is a small snippet of the bytearrays I obtain if I divide the entire file using only NAL headers. I noticed some patterns but I can never guess which sequence is actually starting a full frame.

Decode Proprietary Data GPRMC Data - Yamaha GPS Data logger

This is a long shot, but I have been trying to convert a .ctrk file which has been downloaded from a Yamaha Motorbike Data logger to a readable format.
If I open the file with Notepad++ there is some readable text, mostly the GPRMC data which I can convert to GPS coordinates, speed, time, etc... however the file 'should' also contain 18(i think) other data points(Lean angles, engine RPMs, G forces etc...).
In Notepad++ the data between the GPRMC data just shows as Start of headers, Null, Escape characters,(ENO,DC4,EOT,STX) and such like.

Any ideas how I'd go about decoding this data which I'm assuming is a proprietary format. I have no idea where to start.
Thanks

GMSK transmission issues on GnuRadio

I'm trying to implement rather simple scheme to transfer data from one sdr board to another. I'm using GnuRadio 3.7.14 and my scheme in companion looks like this
Source file is a binary of 96 bytes long and it looks like this

I manually took this piece of output file, so it aligns close to input.
So, here I see two issues (which I believe have one cause):
byte 0xAA (10101010b) switches to 0x55(01010101b) in some part of the message and vice versa
beginning of the message is "sliding" out, there are a 8 bits difference between string 47f0 and 4610
The obvious reason for that is that receiver gets different amount of bits, than sender sends, but I doubt, what exactly leads to this behaviour? How can I debug this to find out what is going wrong?
A couple of words about my setup: I use 3 boards, one USRP B210, one Limesdr-USB and one Limesdr-Mini. I tried this experiment at least in 4 different combinations, including sending from the board to itself, and every time received same result. The boards seems to be ok, they successfully receive fm broadcast and transmit/receive sound by fm from one another.
Thanks!

Actually I found similar question, and recipe given there works for me as well.

failure:/home/ravi/101jssl-h01/openssl-1.0.1j/ssl/s3_pkt.c:615:
Why is it giving a ssl3_write_bytes error and handshake failure?

From the log it is obvious that server does not deal the first message "TLS 1.2 Handshake [length 00dd], ClientHello" properly and does not send the ServerHello message, so it sends an alert which notifies the close of connection to client. The client receives the alert message, and calls ssl3_write_bytes to deal this message. And current status is still in TLS renegotiation. So the handshake function will be called, and give out an error as received message is not expected. This is very clear in code
int ssl3_write_bytes(SSL *s, int type, const void *buf_, int len)
{
const unsigned char *buf=buf_;
unsigned int n,nw;
int i,tot;
s->rwstate=SSL_NOTHING;
OPENSSL_assert(s->s3->wnum <= INT_MAX);
tot=s->s3->wnum;
s->s3->wnum=0;
if (SSL_in_init(s) && !s->in_handshake)
{
i=s->handshake_func(s);
if (i < 0) return(i);
if (i == 0)
{
SSLerr(SSL_F_SSL3_WRITE_BYTES,SSL_R_SSL_HANDSHAKE_FAILURE);
return -1;
}
}

OpenSSL hangs at CONNECTED(00000003)

I am setting up the https connection of my AEM application in a RHEL server hosted in AWS. Followed the documentation provided by Adobe. For the 1st author instance it worked successfully, but on my 2nd server and 3 server, it didnt.
I tried a couple of debugging to make sure that the connectivity is working and that no firewalls are blocking.
When I tried to openssl in debug mode I got the following:
It just hangs and doesn't proceed to the next one like in the 1st server:
2nd Server (with Issue):
openssl s_client -connect localhost:5433 -debug -msg
