Bluetooth with RS232

Post by rodmillermt »

Trying to find a way to communicate with a RS232 port, but it's shaped like a phone port? I'm supposed to purchase a Bluetooth device and pair it with an app, but I've heard terrible reviews on it. So, I'm attempting to just interface with a laptop or something better Bluetooth-wise.

We'll need more specific information to make any useful suggestions.

Strictly speaking, RS-232 is a wiring protocol that doesn't say anything about a data protocol. In practice, RS-232 has been lumped together with the UART data protocol, which is them simplified to a TX/RX signal pair Serial connection.

Bluetooth is a collective marketing term for a family of mostly-incompatible wireless protocols mananged by the same industry group. The ones most commonly found in the field are Bluetooth Classic (BT-C), which is openly unfriendly to hardware hackers, and Bluetooth Low Energy (BLE) which is more hackable.
