Power issues
Using it from either USB or battery hasn't enough juice to make it working properly. It reboot randomly plus the ldo get very hot, not able to provide enough current. It draws about 2W when connected directly to 3.3V, I've also added a 470uF capacitor to a nrf module but the overall problem is that the range is basically limited to no more than 10-15cm, despite the 3 modules working altogether. At this point I think it's a software issue. I've also tried antennas with higher gain but they did little to no difference.
Have you fixed it yet? When I plug it into the computer it says the power source is insufficient or not guaranteed. When I plug it into the usb port with the lamp, the lamp turns off or dims completely.
