RAK11200 upload error

I just got a shipment of RAK11200 modules so that we can test WiFi connectivity with our application. I’ve installed the BSP in Arduino IDE and I’m trying to upload my sketch. I’ve shorted BOOT0 and GND pins and pressed reset prior to the compile + upload step and this is what I get:

Serial port /dev/ttyUSB0
Chip is ESP32-D0WD-V3 (revision 3)
Features: WiFi, BT, Dual Core, 240MHz, VRef calibration in efuse, Coding Scheme None
Crystal is 40MHz
MAC: 34:94:54:bf:c2:f8
Uploading stub...

Stub running...
Changing baud rate to 921600

A fatal error occurred: Invalid head of packet (0xE0)
Failed uploading: uploading error: exit status 2

This was solved by setting the upload speed to 115200.
