Hi Hasan Sorry about the misunderstanding. You want to increase the range of your application, am I correct? If so, which chip are you using? If you're using the nRF52840, you should be able to change the BLE_GAP_PHY setting to BLE_GAP_PHY_CODED, which is "long range mode", a test using this mode is described in this blog post. This mode outputs around 125kbps and is tested outdoors to work at ~1300 meters. If you're using an nRF52832, you could set the BLE_GAP_PHY to always be at BLE_GAP_PHY_1MBPS as well as increasing the TX power for the longest range possible. In both these cases, you should probably remove the change_PHY and PHY_UPDATE events from the main file in the image transfer demo. Best regards, Simon

Hi Hasan

Please write tickets and replies in English here on DevZone, as Turkish is not my strong suit, and Google Translate doesn't always make an understandable translation.

Are you using the Android app that is suggested in the image transfer demo, I don't think the nRF52 will be visible just from the Bluetooth devices, as most phones filter out these devices as "unnecessary"? What Android device are you testing this on, and what Android version are you using? Remember that Android 4.3 or later is required.

Best regards,

Simon

Is there a PIR sensor you support?
0 Simonr over 6 years ago

Hi Hasan

We don't have any PIR sensors we specifically recommend, but most regular PIR sensors should be able to be read by the nRF52 series. Please see this post for suggestions on how to do that. The actual PIR sensor you will have to find yourself. DigiKey might be a good place to start.

Best regards,
