where to see the output of recieved data packets using Gazell protocol

[ali zaidi]

hey, I am new to eval kit and i am asking a very basic question, i want to send the RSSI from PCA10001 board to usb dongle PCA10000.i am looking the examples in sdk for this purpose. now my question is that where we see the packets or bytes recieved in usb dongle...... whether we have to see in nrfgo studio, or some where else.

Hi,

For each packet you receive (or ACK your receive), you can read out the rssi in the gazell callback(s):

void nrf_gzll_host_rx_data_ready(uint32_t pipe, nrf_gzll_host_rx_info_t rx_info);

where nrf_gzll_host_rx_info_t has the rssi:

typedef struct
{
  bool packet_removed_from_tx_fifo;
  ///<  A payload was received in the ACK.
  int16_t rssi;
  ///< Received signal strength indicator in dBm. @sa nrf_gzll_enable_rssi().
} nrf_gzll_host_rx_info_t;

On the gazell device side, you will see this callback:

void nrf_gzll_device_tx_success(uint32_t pipe, nrf_gzll_device_tx_info_t tx_info);

Where nrf_gzll_device_tx_info_t holds the rssi:

typedef struct
{
  bool payload_received_in_ack;   
  ///<  A payload was received in the ACK.
  uint16_t num_tx_attempts;
  ///< Number of attempts used on previous Device packet transmission.
  uint16_t num_channel_switches;
  ///< Number of channel switches needed during previous packet transmission.
  int16_t rssi;
  ///< Received signal strength indicator in dBm. @sa nrf_gzll_enable_rssi().
} nrf_gzll_device_tx_info_t;

You can use the simple-uart library to print these to your PC, and read them out using your choice of serial port terminal.

Cheers, Håkon

lots of thanks for the reply.. please tell me that how i connect more than one host(which is PCA10001 board) with a central device (which is PCA10000) using gazell dynamic pairing example. where i get the individual addresses of all the host devices so that i can access their indvidual RSSI parameters and then send it to the PCA10000 dongle.please help me
