NRF52832 outdoor range.

[tilitililili]

Hello!

I've got a couple of NRF52832 based modules - Holyiot-17095-nRF52832. These modules are presented in the list of supported - https://www.nordicsemi.com/Software-and-tools/3rd-Party/3rd-party-modules. So seems there should be no problems with them.

I've tested outdoor range and I've got near 15m line of sight (no obstacles on the way). There is Holyiot module on one side and phone with nRF Connect App on the other side.

The software I use is the ble_app_uart example with softdevice s132. I also changed the Tx power:

res = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_advertising.adv_handle, 4);

Is it normal that the range is 15m or should it be higher?

Thanks in advance!

Thank you for the update. This placement seems okay to me (might be even better to put in the corner of your design. Can you provide some more details on your software application? Is your application based on any of our SDK examples, and if so, which one? Are you establishing a connection between the phone and the board, or is the board just advertising as a beacon?

Best regards,

Simon

I'm using ble_app_uart_pca10040_s132 example from Nordic examples package nRF5_SDK_15.3.0_59ac345. I only added this in main():

// ........
services_init();
advertising_init();

// Added command    
res = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_advertising.adv_handle, 4);

conn_params_init();
// ........

I also tried enabling/disabling DCDC converter, but it didn't have any effect on performance.
