https://devzone.nordicsemi.com/f/nordic-q-a/14204/sending-data-in-rs232-protocol-to-a-pic-microcontrollerHi all! I want to send data from a beacon (nrf51822) to a Pic microcontroller with the RS232 standard, what function should I use to send data? I have already tried but it seems not to work..en-USTelligent Community 13Tue, 31 May 2016 13:53:10 GMThttps://devzone.nordicsemi.com/thread/54267?ContentTypeID=1Tue, 31 May 2016 13:53:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:aa4cc9d0-35f7-435c-aa99-142f81a2460aMartinBL<p>Hi</p> <p>If you are simply trying to send data between two microcontrollers (via wires) you should look at UART. UART and RS232 is often mistakenly assumed to be the same thing. Read about the difference <a href="http://electronics.stackexchange.com/questions/110478/difference-between-uart-and-rs232">here</a>.</p> <p>We have <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/uart_example.html?cp=5_0_0_4_5_33">UART examples</a> in our <a href="http://developer.nordicsemi.com/">SDK</a>.</p> <p>If you want to emulate a UART bridge over Bluetooth you can look at our <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/ble_sdk_app_nus_eval.html?cp=5_0_0_4_2_2_18">BLE UART example</a>, also found in the SDK.
