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!

Hi

Okay, then the software should not be an issue. And I don't see any issues in how the module is placed either. I think you should contact HolyIoT and ask what the expected range would be for this module. It seems like the antenna may be too close to the other components on the board due to the small form factor, which may reduce the radio's performance.

Best regards,

Simon
