4.2V on the VUSB+ pin are not enough to charge the Li-Po battery?

You may want to go for a different diode with lower forward voltage (e.g. Schottky with 0.2V are the lowest you can typically get)

So as soon as the main board get’s turned on, my particle will wake up to send the newest data?

This seems like a call for a function that is considered undesired behaviour in this thread

Mesh Products in deep sleep wake on USB/VIN power state change

reading the data sheet for the nrf I found the following statement “When VBUS rises into its valid range while the device is in System OFF, the device resets and transitions to System ON mode”. Looking at the schematic the Vbus pin is directly connected to the vbus of both the usb and the nrf, so this will always wake the device (And feed back into the PC!) which begs to wonder why this was used instead of connecting it the vin side of the lipo charger after the protection diode. So to me looks…
