Hi, i have several problems to use my nrf52840 PDK wirelessly.
I have made a project of a star network, in which the peripherals send by NUS the data they collect from digital and analog sensors. This works perfectly if all nrf52840 PDK peripherals are connected via micro usb.
Obviously I want the project to be wireless, and when I tried to use the nrf52840 PDK with just the coin cell, nothing of the board worked, I tried all possible combinations of switches and not even turn on the LED1. Mention what happens to me with the four nrf52840 PDK that I have and by the way, the batteries are fully charged.
Also say that if they work only with batteries, with the example blinky or ble_hrs, although the LEDs don`t shine with such intensity that connected via USB
Therefore, I tried to use a li-po battery but nothing works either, I have also tried the different combianciones of the switches and nothing. The only thing that I have achieved for that function is to connect the micro USB and the li-po battery and place the switch SW9 in VDD, then I disconnect the micro USB, then everything works.
I do not know what I'm doing wrong or if the problem is plaque, someone can help me
