How to specify the connection interval via the client?

[stackGreen]

Hi,

I want to maximize the indication data throughput and minimize the latency with 4 connected devices.

Setup:

I’m using a nrf52840 as a ble client (sdk 15.2) that is connecting to 4 ble servers (nrf52832 sdk15.2).

The servers are transmitting ble data via indications.

Question:

The client is negotiating the connection interval to 30ms. Due to Latency reduction, I want to reduce the connection interval.

Is there a possibility to do that from the central device?

 

Thank you,

Arthur

 Yes.

The client is negotiating the connection interval to 30ms.

 This is the default max value used by the scan module when a connection is established. You can change this by modifying the value of NRF_BLE_SCAN_MAX_CONNECTION_INTERVAL in sdk_config.h

You can also change the connection interval by using the function sd_ble_gap_conn_param_update()
