Looking for a little help with RAK 4600 eval kit

LPWAN Modules / EVBs RAK4600

I’m having issues with trying to upload some basic code to my RAK4600 eval kit.

I’m using VS with PlatformIO and I’m getting the following error?

Upgrading target on COM35 with DFU package c:\Users\veitchb\Documents\PlatformIO\Projects\rak\.pio\build\adafruit_feather_nrf52832\firmware.zip. `Flow control is disabled, Single bank, Touch disabled`

Timed out waiting for acknowledgement from device.
Failed to upgrade target. Error is: No data received on serial port. Not able to proceed.

I then tried using the serial tool to see If I could communicate with the board with a simple command like
>>at+version

And I get nothing back?

Any help would be appreciated.

Hi，

You want wo develop own firmware? If so, I advise you use our online develop system:

As for the serial tool, it needs flow control(DTR). So you can use this:

Did you set the MCU in bootloader mode?

  1. Connect the pin 18 of MCU to the GND.
  2. After restarting the MCU, disconnect pin 18 from GND. The current state is bootloader mode.

If you use a WisBLOCK board (RAK5005), the silk screen of pin 18 on the back of the board is " RX1 ".
