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 ?

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.

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.
