RAK 2287 not connecting to TTN due to failed to set SX 1250_0 in STANDBY_RC mode

I am using this LORA gateway, 2287 SPI, RAK Raspberry Pi 4 Kit for LoRaWAN – RAKwireless Store. I am following this tutorial: Quick Start Guide for Raspberry Pi and RAK LPWAN Concentrators | RAKwireless Documentation Center . I am getting an error that is preventing me to connect to the TNN server. Anyone have any suggestions. I used option 7, RAK 7248 no LTE (RAK 2287 SPI+Raspberry Pi), as my RAK version. The error is “Failed to set SX1250_0 in STANDBY_RC mode.” Thank you
