Ebyte NRF52805 module
Hi, I see you integrated the E104-BT5005A BLE chip in this project.
I’m trying to use it in a simple robot project and having difficulties to make the RX/TX connection with “RF Connect” IOS app.
I already wired the chip to the Seeeduino board and I can find and connect the bluetooth on the RF scan list. But I just don’t know the Arduino code to make it send and receive simple massages on the Arduino serial monitor.
Your help is very much appreciated.
I've often wondered at what rate 18650 cells are discharged to arrive at their capacity ratings? It's well known that discharging at a slower rate will yield a larger apparent capacity. Of course, a quality battery would show the actual curves in its datasheet.... but in cases where there's just a single number given, and no context, I wonder how it's done?
