Improve Range

[Muqarrab]

Hi,
1- I have worked on ble_app_template(As Peripheral Only). Now, what changes I should make to gain max range? Any specific changes for long-range? 
I have already set this but not getting more than 50 feet range.

    uint32_t err_code = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_advertising.adv_handle, 8); 
    APP_ERROR_CHECK(err_code); 

5556.main.c

2- Here is my code. I have read this blog Long_Range. But not finding where I have to make changes in my code. Can you please guide me? As I am developing devices that control from
the mobile app. I need support for both mobiles that have Bluetooth 4 and 5. I have searched a lot but not getting clear answers. please suggest

Hi,

1. The range will depend on a lot of factors, including output power, board design, selected PHY, environment, noise, etc. If you are indoors in a noisy environment with lots of obstacles, you may not be able to get better range without additional HW like power amplifiers etc.
2. Have you seen these examples?
