E.Yuval Sinay MVP COMMUNITY SOLUTIONS CONTENT DISCLAIMER To avoid this behaviour, for example if you wish to use Serial1 to talk to a device while disconnected from USB, explicitly set the console serial port using tConsole during the init event which Espruino runs on boot. My code works when I'm connected via Bluetooth but stops when I disconnect.Espruino works when connected to a computer, but stops when powered from something else. ![]() ) will no longer get called.Ĭheck out the following for more information: When the console is on a port, a listener added with SerialX.on('data'. the left-hand side of the IDE) when not connected to something else like USB or Bluetooth. Software serial reception will become increasingly unreliable the higher the CPU load.īy default, Espruino may end up using one of the Serial ports (usually Serial1) for the console (eg.Sending more than one or two characters will block execution of other JavaScript code until completion (hardware serial ports have a ~100 byte transmit buffer).Baud rates significantly above 9600 baud are unlikely to be reliable.NOTE: As software serial doesn't use dedicated hardware there are some compromises: However software serial doesn't use ck, cts, parity, flow or errors parts of the initialisation object. This can be used on any pin, and you can have multiple instances of Software serial ports. To do a quick 'loopback' test, connect the RX and TX pins together on one of the serial ports (for example Serial1), and then run the following code: tup(9600, ) for transmit only If you specify an rx pin but not a tx pin (or tx but not rx) then ck and cts are not used unless specified. (usually the lowest numbered pins on the lowest port that supports If not specified in tup, the default pins are used for rx and tx The nRF52 based Bluetooth Espruino boards) the UART can be used on any pin so won'tīe explicitly marked, but others (such as the STM32 based Espruino boards) only ![]() You can find out which pins to use by looking at your board's reference pageĪnd searching for pins with the UART/ USART markers. See the Serial Class and tup(.) in the Reference.
