ESP32 AT firmware and BLE sleep mode

[Davide_Tallone]

Hello everybody.

I'm currently evaluating a ESP32-WROOM-32U for a BLE application, and I am quite confused about the current status of compatibility between the BLE and light sleep mode.

I am using the AT comands firmware and from what I'm seeing, while the light sleep mode work without any issue in WIFI, the same cannot be said for the BLE, where the average current consumption is sitting around 100mA.

Is there any way that i am missing to enable the sleep mode while using the BLE connectivity?

Here is the setup that I am currently using:
ESP32-WROOM-32U
ESP32-DevKitC-32UE
factory_WROOM-32.bin V2.1

Code used
AT Instruction Set and Examples.pdf "9.5.2.2. UART-BLE Passthrough Mode" with a AT+SLEEP cmd sent before every other AT cmd in the example.

Thank you for your patience.
