distance between two nrf52832

[manikandan]

hello 

i am using two customised nrf52832 and trying to get the maximum distance between two boards people suggested me this example https://github.com/NordicPlayground/nRF52-ble-long-range-demo but i found that nrf52832 supports only 4 dbm so i cant use this example as this example specified for nrf52840 my question

1)what is the maximum distance achievable between nrf52832

2)is there any example for this?

thanks and regards

Hi, 

The long range mode is not supported in the nRF52832, only in the nRF52840. You can refer to this post for the distance although it's for nRF52840.

thanks for your reply amanda as i am using two nrf52832 devices i could not use that link  what i am doing now is flashing ble_app_uart_c in one board and ble_app_uart in other and i can sucessly establish a connection between two boards and iam 

  advertising_start();
     uint32_t err_code = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_advertising.adv_handle, 4);

using this function to increase the tx power my question is 

1)do i have to include this function both in central and peripheral??

2)and where can i get the rssi values between the devices in central or peripheral??

3)which function i can use to get the rssi values between the devices

what i am trying to do is get the rssi value and print it in console how can i achieve this

thanks and regards

See this post https://devzone.nordicsemi.com/f/nordic-q-a/19437/rssi-measurement-for-each-peripheral-s130-or-132/75493#75493

If the device is the central, it measures the RSSI based on the packet it received from the peripheral.

If the device is the peripheral, it measures the RSSI based on the packet it received from the central.

 In order to measure the RSSI on a connected peripheral, you can use the SoftDevice functions sd_ble_gap_rssi_get(), sd_ble_gap_rssi_start() and sd_ble_gap_rssi_stop(). You can use sd_ble_gap_rssi_start to get RSSI once you're in a connection. Read more about these functions here.
