How do I use two antennas with a single Bluetooth module? (BLE repeater)

I am working on a project that uses small Bluetooth low energy (BLE) beacons to track important items. Is there a way to connect two antennas to a single BLE module that could either listen/broadcast on both antennas or multiplex between the two? Or any other idea?

What kinds of test is suitable for low volume PCB order?

I’ve ordered fabrication and assembly of small PCB batches (100st) a couple of times already. Each time the factory asked me if I want to do test on the PCB. But I don’t what to do about it. And I test them by myself. Vervolgens, the result of the testing is unacceptable with 15% soldering problems. So bad. I think I will ask the supplier to test them before delivery.

Kan ik een printplaat maken zonder grondvlak??

Recently we are developing a portable device which should be very tiny and light. In terms of PCB design, I am thinking whether it is a good idea to exclude ground plane to minimize the product size.
