Hello,
After decided and tried porting nrf_esb from the example code to my project, now I am stuck with changing the content of the payload.
I changed the payload using:
for (uint8_t i = 0; i < tx_payload.length; i++) {
tx_payload.data[i] += 1;
// printf("tx_payload.data[%d]: %x\r\n", i, tx_payload.data[i]);
}
And here's my handler:
void nrf_esb_event_handler(nrf_esb_evt_t const * p_event) {
nrf_gpio_pin_toggle(LED_2);
printf("handler\r\n");
// NRF_LOG_INFO("Inside handler!");
// NRF_LOG_FLUSH();
switch (p_event->evt_id) {
case NRF_ESB_EVENT_TX_SUCCESS:
// NRF_LOG_INFO("Packet sending succeeded!");
printf("sent? PID: %x\r\n", tx_payload.pid);
nrf_esb_pop_tx();
break;
case NRF_ESB_EVENT_TX_FAILED:
(void) nrf_esb_flush_tx();
(void) nrf_esb_start_tx();
//NRF_LOG_INFO("Packet sending failed!");
break;
case NRF_ESB_EVENT_RX_RECEIVED:
// Get the most recent element from the RX FIFO.
while (nrf_esb_read_rx_payload(&rx_payload) == NRF_SUCCESS) {
printf("Received a packet. ID: %x:\r\n", rx_payload.pid);
for (uint8_t i = 0; i < rx_payload.length; i++) {
printf("rx_payload.data[%d]: %x\r\n", i, rx_payload.data[i]);
}
// Set LEDs identical to the ones on the PTX.
// NRF_LOG_INFO("Packet Received!");
}
//nrf_esb_flush_rx();
break;
}
// NRF_LOG_INFO("Exit!");
// NRF_LOG_FLUSH();
//nrf_gpio_pin_toggle(LED_2);
}
Every time a "send packet command" is fired, it should increment the content inside tx_payload by 1 then send it.
Upon printing data, it always print the old data. Printing on the receiver will not happen if I did not fire sending on sender. The only way to print a new data is to reset it first.
Is this the correct way to use nrf_esb? or is it not?
Thank you,
Winz
