RAK811 - Firmware v3 - Baud rate change

what is the use of boot mode ?

The boot mode is used to firmware update.

i have used the code in : https://github.com/RAKWireless/WisNode-Arduino-Library

for now i didn’t have removed any resistors from the wisnode. and i have tried uploading the code in link but it failed to upload to the arduino

my connection’s are:

jumpers: RXD -> TX , TXD -> RX
TX (wisnode) -> CRX
TX (ARDUINO) -> TX (wisnode)
RX (ARDUINO) -> RX (wisnode)

my firmware version is
Firmware Version: RUI v3.0.0.12.H

Hi,

Pin11(Arduino)->CRX(wisnode)

i was able to make a connection by connecting wisnode directly to the computer and passing the commands. i saw the data that i send in the thingsnetwork

then i changed the jumpers (to connect with arduino) and i was not able to upload the code to arduino .
and im stuck here.
till now i tried all my experiments without removing any resistors from the wisnode board.

now im trying to connect wisnode directly over the arduino. so, for that which all components i should remove from the wisnode board.

i different instructions it says different components.

please give me a complete idea.

i have buyed a usb to ttl converter.
