Hi there,
I'm working on nrf52840 & NCS 2.0.0. Sometime I can not get a NRF_RADIO_EVENT_END event so the while loop under the radio_tx function will be stuck.
Is there any suggestions?
void radio_tx(uint8_t channel, uint8_t pattern, uint8_t *packet)
{
radio_disable();
radio_config(pattern);
nrf_radio_mode_set(NRF_RADIO, NRF_RADIO_MODE_BLE_1MBIT);
nrf_radio_shorts_enable(NRF_RADIO,
NRF_RADIO_SHORT_READY_START_MASK |
NRF_RADIO_SHORT_END_DISABLE_MASK);
nrf_radio_packetptr_set(NRF_RADIO, packet);
nrf_radio_txpower_set(NRF_RADIO, RADIO_TXPOWER_TXPOWER_Pos4dBm);
nrf_radio_frequency_set(NRF_RADIO, CHAN_TO_FREQ(channel));
nrf_radio_event_clear(NRF_RADIO, NRF_RADIO_EVENT_END);
nrf_radio_event_clear(NRF_RADIO, NRF_RADIO_EVENT_READY);
//nrf_radio_int_enable(NRF_RADIO, NRF_RADIO_INT_END_MASK);
// printk("NRF_RADIO_INT_END_MASK\n");
nrf_radio_task_trigger(NRF_RADIO, NRF_RADIO_TASK_TXEN);
while(!nrf_radio_event_check(NRF_RADIO, NRF_RADIO_EVENT_END)) {
// wait for transmit tx packet
}
}
static void radio_config(uint8_t pattern)
{
uint8_t playload_length;
nrf_radio_packet_conf_t packet_conf;
nrf_radio_modecnf0_set(NRF_RADIO, true, RADIO_MODECNF0_DTX_Center);
nrf_radio_txaddress_set(NRF_RADIO, 0);
nrf_radio_rxaddresses_set(NRF_RADIO, 1);
switch (pattern)

nrf_radio_crc_configure(NRF_RADIO, RADIO_CRCCNF_LEN_Two, NRF_RADIO_CRC_ADDR_INCLUDE, 0x880083);
