Hi,
I am using bq25703A for the battery Charger. I manage to establish a communication between this module and the card STM32F4 .
The communication is well established and I manage to write and read data in the registers of bq25703A also I manage to charge a battery that consists of 3 cells now I try to unload the same battery.
I followed the activation steps of the OTG and I finally succeeded, but my initial problem was the discharge of the battery.
When I activate the OTG the discharge will be done directly or it is necessary to add a charge.
If yes, how can I add the charge? in the datasheet there is a part that says "The device supports USB OTG operation to deliver power from the battery to other portable devices through USB port "but where is the USB port I do not see?
Regards,
Mohamed
