nRF51 Broadcast advertising

[RahulR]

How to

1. increase advertising frequency - Which BLE GAP parameter should be updated?

2. increase RSSI signal strength - My device is not battery operated, so there are no power constraints.

Thanks,

Rahul

Hello Rahul,

1. increase advertising frequency - Which BLE GAP parameter should be updated?

To increase advertising frequency you will need to reduce advertising interval, the minimum value is 20 ms. Keep in mind that there is added a random delay between 0 and 10 ms before every advertisement, as part of the BLE specification.

2. increase RSSI signal strength - My device is not battery operated, so there are no power constraints.

You can change your TX power using the SoftDevice function sd_ble_gap_tx_power_set.
Which TX power levels is supported will depend on which nRF51 SoC and SoftDevice you are using.

Best regards,
Karl
