ESP32 Forum

Hello.

Our application is a BLE HOGP (HID Over GATT Profile) remote control with target current draw <200uA.

BLE HOGP Support
Can you please advise whether BLE HOGP example application(s) are available for the ESP32? If so, please forward relevant URL(s).

Device Selection
We don't require Wi-Fi, so perhaps the ESP32-H2-MINI-1 modules are suitable for our application. ESP32-H2-MINI-1 light-sleep current is <100uA, so if the ESP32 is mostly in this mode, e.g. wake every 10 seconds for <100ms at <10mA, total current drawn would be <200uA. However, this relies on a BLE connection being maintained in light-sleep.

Using an external 32kHz crystal you should be able to keep Bluetooth 'connected' during light sleep.

. However, following implementation, the current draw was found to be too high.

Low Power Requirement
Can you please advise whether our power requirement can be satisfied using ESP32-H2-MINI-1 devices? If so, please advise necessary configuration settings.

Thank you.

BLE HOGP Support
Thanks for the URL 'Microcontroller'.

Low Power Requirement
Confirmation that a BLE connection can be maintained while drawing <200uA using ESP32 modules with appropriate use of power modes, such as light-sleep, would be appreciated.
Confirmation might be:
From someone who has maintained a BLE connection while drawing <200uA
and / or
Advice about appropriate configuration settings.

Thanks.
