https://devzone.nordicsemi.com/f/nordic-q-a/42057/what-should-i-do-in-nrf-52832-to-enable-rs485-communicationHi. I have a problem with using RS485 (ISO-3082DWR) from NRF-52832. The SDK version uses 15.02. Here&#39;s the code I&#39;ve run. nrfx_uart_config_t uart_config = { .pseltxd = 30, .pselrxd = 31, .pselcts = 19, .pselrts = 18, .p_context = NULL, .hwfc = NRF_UART_HWFC_DISABLEDen-USTelligent Community 13Fri, 04 Jan 2019 09:56:21 GMThttps://devzone.nordicsemi.com/thread/163915?ContentTypeID=1Fri, 04 Jan 2019 09:56:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e09535eb-21bf-4d0c-9547-445e32d79fa2J&#248;rgen Holmefjord<p>Hi,</p> <p>Why do you call&nbsp;<span>nrfx_uart_tx_abort&nbsp;immediately after&nbsp;nrfx_uart_tx? The UART driver operates in non-blocking mode, meaning that calling nrfx_uart_tx will only setup the transfer&nbsp;before returning, the transfer itself will not have completed until you get the event in the event handler. If you call abort, you will terminate the transfer before it has started.</span></p> <p><span>Best regards,<br />Jørgen</span></p><div style="clear:both;"></div>
