@hemalchevli what's up dude do you have experience with routing CAN signals?

techielew•11/19/24, 10:08 AM

Also we need to touch base on the PCB design series yo

melta101•11/19/24, 10:08 AM

lots of stuffs incoming
i see

it's a hacking session, we just wanna hang out and make you feel weird as you code, thats what we do to everyone there, we just question your identation and semicolons

ZacckOsiemo•11/19/24, 10:11 AM

@melta101 basically you don't have to wait until it is upstream

ZacckOsiemo•11/19/24, 10:12 AM

Also trying to get few patches upstream in linux kernel
lets hope they approve

ZacckOsiemo•11/19/24, 10:16 AM

wait dude, how many things are you working on

techielew•11/19/24, 10:16 AM

yeah what patches

ZacckOsiemo•11/19/24, 10:16 AM

You can review one of those patches

Ttechielew yeah what patches

melta101•11/19/24, 10:17 AM

removing redundant code in few driver
they are very old drivers lol

techielew•11/19/24, 10:17 AM

WTH it's 3 AM on a school night I must away.

melta101•11/19/24, 10:20 AM

oh btw
could you look into the SPI prob i have
when you are free

melta101•11/19/24, 10:20 AM

Thanks in advance

Mmelta101 oh btw could you look into the SPI prob i have when you are free

hey , i was researching about paring iot options like we you get into a certain range than that iot protocol used in that area will get auto paired(first time pair object) to your phone and then you can access it . i am unable to find any such options , do anyone have idea about it ?

ZacckOsiemo•11/19/24, 11:53 AM

@32bitSaviour isnt this this sessionless BLE or what did you call the beacon thing?

Marvin•11/19/24, 12:03 PM

Hey. Yes. You can opt for a connectionless BLE beacons arranged well can broadcast locations very effective depending on which beacon your phone is in range with.

Been working with the bruce firmware here https://github.com/pr3y/Bruce
I have had fun with BLE and WiFi.
It is easy to clone an access point and get devices to connect to it in guise of the legitimate network.
You can show feed them custom HTML to steal credentials. It is scary what malicious actors can do with search devices.
I just got the Nordic nRF24L01, I will connect it to test our bruce's nrf jammer.

Yup, I have designed few automotive PCBs

Hey @Dhruv
Welcome to DevHeads.
Is there something you are currently working that you can share with us?

Dhruv•11/20/24, 7:27 AM

surely will do share it in sometime. @32bitSaviour .

Dhruv•11/20/24, 7:52 AM

currently I am working on FEIG payment devices, which uses nfc cards for the metro rail ticketing systems. other part I am working on linux background services for my python scripts.

Marvin•11/20/24, 7:56 AM

Nice. I also work in payments. With EMVco type payment devices most running on top of a embedded Linux OS.
At what level do you work bare-metal, RTOS or embedded Linux?

Dhruv•11/20/24, 8:01 AM

Actually I am working on top layer. not inside the feig device itself. so, basically I had a top layer code which is already working. I am trying to understand the code, flows only.

Dhruv•11/20/24, 8:02 AM

I have the code that read and write data to card and validate it using apis.

Dhruv•11/20/24, 8:03 AM

I am not working on device's core functionality.

hardware design would be hard since I am mostly software guy but I can discuss about differential si
