WL1835MOD: Unable to power on Bluetooth at wl1835mod after update of WL18XX-BT-SP

Part Number: WL1835MOD
Other Parts Discussed in Thread: WL18XX-BT-SP

Hello Forum,

I have an issue with an wl1835mod after update of WL18XX-BT-SP — Bluetooth service pack for WL18xx
Version: v4.7
Release date: 20-May-2021

I'm not able to power on the bluetooth with this version.
I tried it with the tool LinuxDEVM provided by TI and got the error:
DEVM>SetDevicePower 1

echo 1 > /sys/class/gpio/gpio63/value
