So I’m trying to send data from and Rtksimple V3.0 to an Esp32 board by connecting them with wires. I’ve connected the Arduino RX pin to the Rtksimple TX and viceversa, I also connected the esp32 3V3 pin to the Rtksimple ioref and connected both GNDs. The Rtksimple has no additional configuration aside from the factory one, though looking at the config files in ublox u-center it suppossed to send to the same messages it does through the usb, since the MSG (Messages) tab shows that all the messages that go out are checked to go through all the available ports: l2C, UART1, UART2, USB, SP1. I have connected the Rtksimple board to PC with usb and can read the data from there but when I connect it to the Esp32 with wires nothing happens. The Esp32 is programmed to
but nothing happens. So, how does one connects an Rtksimple V3.0 board to another Arduino board, in this case an esp32 and sends data to it? Is it enough to connect the rx,tx,ioref and gnd? Am I missing something?
