I have an issue with my RAK811 when I try to control it through an Arduino Nano.
I already have a RAK831 gateway that works perfectly and I already succeed to send packets with my RAK811 module through RealTerm when the module is directly connected to my computer (with the right position of the jumper on P6 : CRX-TXD and CTX-RXD)
The issue appears when I try to do this directly with the Nano connected to the computer and the RAK811 connected to the Nano like below and I don't think I made mistakes in the connections (5V to 5V, GND to GND and TX to D11 & RX to D10) as it is explained on the user Guide (as the connection between RX and TX is already internally made in the RAK811). And I also though to move the jumper position on P6 and put it between TXD-RX and RXD-TX.
When I upload the JoinNetworkOTAA.ino sketch I obtain the following result:
I really don't understand why I don't have the response of the RAK811 as I get them when I use it directly with realterm through my computer.
Could someone help me ?
