how to test NRF51822 transport data rate

Question

now I used sample code of radio 
 
 
 change NRF_RADIO->MODE = (RADIO_MODE_MODE_Nrf_2Mbit << RADIO_MODE_MODE_Pos)； 
 
 
 In transmitter code , I change 
 while (true)
{
send_packet();
packet ++;
nrf_delay_ms(1);
__WFE();
} 
 
 
 In receiver code , I change 
 int oldrecv = -1;
while (true)
{
uint32_t received = read_packet();
if(oldrecv != received-1)
{
NRF_LOG_INFO("%d
", received);
NRF_LOG_FLUSH();
oldrecv = received;
}
err_code = bsp_indication_set(BSP_INDICATE_RCV_OK);
APP_ERROR_CHECK(err_code);
} 
 
 
 result. Transport data 1KB/S, Data lose is about 80%. 
 
 
 question1, is my test right? 
 
 
 question2, how to solve this problem？ 
 
 
 question3, how to test 2M bit ?

Hi 
 What is your end goal of this exercise? 
 If you are planning to implement an application later on I would strongly recommend using an RF library, such as the nrf_esb implementation available in the SDK.
Then you will get features such as FIFO buffering, acknowledgements and packet re-transmission for free, and you don't have to focus on the low level radio handling. 
 If you use 255 byte payloads you will get pretty high data rates, and you can increase it even more by disabling the acknowledgement feature (even though you won't detect packet loss anymore).
