NOTIFY not in HEX and cannot be stopped

[Bmooij]

Environment

• Module or chip used: ESP32-WROVER
• IDF version (run git describe --tags to find it): v4.0.1-193-ge7ac221b4
• Build System: Make
• Compiler version (run xtensa-esp32-elf-gcc --version to find it): xtensa-esp32-elf-gcc (crosstool-NG esp-2019r2) 8.2.0
• Operating System: Windows
• Power Supply: USB external 5V

Problem Description

The command AT+BLEGATTCWR=0,4,2,1,2 starts notifying, but the values are not in HEX. And cannot stop the notified messages.

Expected Behavior

I would expect +NOTIFY:0,4,2,20,<HEX>

Actual Behavior

Actual Behavior +NOTIFY:0,4,2,20,<RAW Bytes>

Steps to repropduce

1. AT+BLEINIT=1
2. AT+BLECONN=0,"<remote_address>"
3. AT+BLEGATTCWR=0,4,2,1,2

// It helps if you attach a picture of your setup/wiring here. Bluetooth Characteristics for 0,4,2 +BLEGATTCCHAR:"char",0,4,2,0x<UUID>,0x34 +BLEGATTCCHAR:"desc",0,4,2,1,0x2902

Writing {0x01, 0x00} should start the notifieer and writing {0x00, 0x00} should stop the notifieer

Just verified this affects ESP32-WROOM as well.
