Query on the BLE signal penetration through metal sheethttps://devzone.nordicsemi.com/f/nordic-q-a/85665/query-on-the-ble-signal-penetration-through-metal-sheetDear Concern, We are using nrf52840 USB dongle as one of the components in of our products. There is a chance that the device can be put inside a metal container. Right now I will need two information which are critical in our developments. 1.

If possible there should be some opening in the metal enclosure around the antenna to reduce the impact on the strength of the received signal. This opening can be filled with a non conducting material as completely enclosing the antenna will block most of the RF signals.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Bendik</p><div style="clear:both;"></div>
