when nrf52840 adds long range,mobile receiving the broadcast is slow

[danny_zhang]

Hi,

   I use sdk153.IC is nrf52840.

  Install NRF connect on Android phones such as Samsung vivo oppo. Only Samsung can quickly scan the broadcast and the connection is normal, while vivo oppo takes more than 10 seconds to receive the broadcast name. It is confirmed that these phones support long range. Without adding long range, their scanning connections are normal.Is the compatibility so poor?

Regards,

Danny

You should check the scan settings in the nRF Connect app, and make sure they are the same on all the phones you are testing. If the settings are the same, then it seem to be an performance issue with these "Vivo" and "Oppo" phones.
