nrf52840 DK problèm to pairing back ?

[chantal thibaud]

Hello, I'm just starting to experiment bluetooth with the nfr52840 DK board and the sample programs available, especially those "ble peripheral" and as a beginner I started by doing a pairing that succeeded after a first programming and then I I forgot the device to pairing again and there not possible ?

Only if I reprogram the board I can again match the board but no later ...? do I need to put the board in pairing mode to pair it with my phone? is there a process for that ?

i try the soft : 

\nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\experimental\ble_app_hrs_nfc_pairing

nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_alert_notification

why don't pairing after to have forget ? 

Thank for your answers

Best regard

 And what is your need exactly?

We want to connect a tablet or smartphone in bluetooth, previously paired with an electronic control (board the chip nrf52) to control power such as light, heating elements, or other ...

For this, the question is BLE or B5? would be the most judiciously interresting?

Thank you

"We want to connect a tablet or smartphone in bluetooth, previously paired with an electronic control (board the chip nrf52) to control power such as light, heating elements, or other ..."

I suggest you take a look at the BLE Blinky Application together with nRF Connect for Mobile, a reference BLE application for Android and iOS. 

"For this, the question is BLE or B5? would be the most judiciously interresting?"

Well Bluetooth LE is much better suited for control applications than Bluetooth EDR, both are present in the Bluetooth 5.0 specification. We only support BLE as BEDR is not nearly as energy-efficient, and BLE can cover most, if not all, uses-cases that BEDR has.
