nrf52832 BLE_GAP_PHY_2MBPS configuraion in ble_app_uart peripheral mode

[adnan arshad]

Hi,

I want to configure "BLE_GAP_PHY_2MBPS"  in  ble_app_uart example of sdk 15.3.0 for faster communication, for this i have changed 

BLE_GAP_EVT_PHY_UPDATE_REQUEST:
{
//NRF_LOG_DEBUG("PHY update request.");
ble_gap_phys_t const phys =
{
.rx_phys = BLE_GAP_PHY_AUTO,
.tx_phys = BLE_GAP_PHY_AUTO,
};
err_code = sd_ble_gap_phy_update(p_ble_evt->evt.gap_evt.conn_handle, &phys);
APP_ERROR_CHECK(err_code);

To

BLE_GAP_EVT_PHY_UPDATE_REQUEST:
{
//NRF_LOG_DEBUG("PHY update request.");
ble_gap_phys_t const phys =
{
.rx_phys = BLE_GAP_PHY_2MBPS ,
.tx_phys = BLE_GAP_PHY_2MBPS ,
};
err_code = sd_ble_gap_phy_update(p_ble_evt->evt.gap_evt.conn_handle, &phys);
APP_ERROR_CHECK(err_code);

But it does not effect on the overall time taken by 180 bytes to read and write.

Is there some thing else needs to change to configure BLE_GAP_PHY_2MBPS  communication.

Thank you Edvin,

I only need to call the changed snipped in the BLE_GAP_EVT_CONNECTED event and the BLE_GAP_EVT_PHY_UPDATE_REQUEST code will remain same with no change? am i correct???.

Yes. Also, make sure that the other device supports 2MBPS. If it is another nRF you need to have either BLE_GAP_PHY_2MBPS or BLE_GAP_PHY_AUTO in the BLE_GAP_EVT_PHY_UPDATE_REQUEST event.
