config STack frame to used ack correctly

[pawelm87]

Hi,
I try used STack frame and send ack to make sure that reciver got the packet. When I set all in spirit1 what is necessary I got this situation:
TX -> sends packet -> IRQ packet lost. This means that ACK packet from receiver don't recive packet.
RX -> gets packet and sends ACK -> IRQ packet read and IRQ packet sends.

my setting:
RX:

#include "mbed.h"
#include "mbed-trace/mbed_trace.h"
#include "SimpleSpirit1.h"
using namespace std;
#define MBED_TRACE_MAX_LEVEL TRACE_LEVEL_DEBUG
#define TRACE_GROUP "main"
#define SPIRIT_BUF_LEN (95)
DigitalOut led(LED1);
static SimpleSpirit1 &radio = SimpleSpirit1::CreateInstance(PIN_SPSGRF_MOSI,
PIN_SPSGRF_MISO,
PIN_SPSGRF_SCLK,
PIN_SPSGRF_IRQ,
PIN_SPSGRF_CS,
PIN_SPSGRF_SDN,
PIN_SPSGRF_LED);
static char read_buf[SPIRIT_BUF_LEN];
static volatile bool rx_done_flag = false;
static void callback_func(int event)
{
if(event == SimpleSpirit1::RX_DONE)
{
rx_done_flag = 1;
}
}
int main()
{
mbed_trace_init();
tr_info("---START---");
radio.attach_irq_callback(callback_func);
PktStackInit stackInit={
PKT_PREAMBLE_LENGTH_08BYTES, // preamble length in bytes
PKT_SYNC_LENGTH_4BYTES, // sync word length in bytes
0x1A2635A8, // sync word
PKT_LENGTH_VAR, // variable or fixed payload length
7, // length field width in bits (used only for variable length)
PKT_CRC_MODE_16BITS_2, // CRC mode
PKT_CONTROL_LENGTH_0BYTES, // control field length
S_DISABLE, // FEC
S_ENABLE // whitening
};
SpiritPktStackInit(&stackInit);
SpiritPktStackAutoAck(S_ENABLE, S_DISABLE);
radio.on();
SpiritTimerSetRxTimeoutCounter(0);
SpiritTimerSetRxTimeoutPrescaler(0);
SpiritTimerLdcrMode(S_DISABLE);
while (true) {
if(rx_done_flag)
{
memset(read_buf, 0, SPIRIT_BUF_LEN - 1);
read_buf[SPIRIT_BUF_LEN-1] = '\0';
rx_done_flag = false;
int ret = radio.read(read_buf, 58);//sizeof(read_buf));
printf("Received a packet Received string = '%s' (len=%d)\r\n", read_buf, ret);
SpiritIrqs pxIrqStatus;
SpiritIrqGetStatus(&pxIrqStatus);
}
}
}

TX:

#include "mbed.h"
#include "mbed-trace/mbed_trace.h"
#include "SimpleSpirit1.h"

SpiritPktStackInit(&stackInit);
SpiritPktStackRequireAck(S_ENABLE);
while(1)
{
radio.on();
tr_debug("radio on");
while(radio.is_receiving());
tr_debug("radio recive");
size_t curr_len = strlen((const char*)send_buf) + 1;
radio.send(send_buf, curr_len);
tr_debug("send");
uint8_t i = 10;
while(i--)
{
wait_ms(1);
uint8_t reg;
SdkEvalSpiReadRegisters(0xc1, 1, &reg);
tr_debug("spirit status %x", reg>>1);
if(reg>>1 == 0x33)
tr_debug("ready...");
break;
}
radio.off();
tr_debug("radio off");
if (tx_done_flag)
{
tx_done_flag = false;
tr_info("**Packet sent *** Sent string ='%s' (len=%d)", send_buf, strlen((const char)send_buf) + 1);
}
wait(10);
}
}

In TX I enable ACK field and in RX I enable autoack, but this don't work correctly. Interrupt sends data never occurd in TX. When I turn off RX and set retransmision feature, again never occurd IRQ max retransmision.

Someone can check my setting and tell my how correct config radio. What I need to set in register in RX and TX.
