I have an NRF24LE1 transmitter using ESB. It is sending a static payload of 10 bytes every sec. The other configurations on the transmitter are: RF channel:2, CRC: 1 byte, DataRate: 1MBPS.
I am trying to understand the given example code for esb_prx for NRF52-DK in NRF5 SDK 11.0. which I am using as Receiver.
It seem dynamic payload length - DPL is used as a default configuration. Can I use dynamic payload to talk to my current transmitter which has static payload ? What is dynamic payload mean, does it mean I can send any number of bytes to the Receiver? If so, payload_length field of nrf_esb_config_t in Receiver become irrelevant in DPL mode.
On a side question about esb_ptx in NRF52-DK:
#define NRF_ESB_CREATE_PAYLOAD(_pipe, ...) \
{.pipe = _pipe, .length = NUM_VA_ARGS(__VA_ARGS__), .data = {__VA_ARGS__}}; \
STATIC_ASSERT(NUM_VA_ARGS(__VA_ARGS__) > 0 && NUM_VA_ARGS(__VA_ARGS__) <= 63)
static nrf_esb_payload_t tx_payload = NRF_ESB_CREATE_PAYLOAD(0, 0x01, 0x00, 0x00, 0x00, 0x11, 0x00, 0x00, 0x00);
What will be the pipe number, length and data values using NRF_ESB_CREATE_PAYLOAD macro ? But nrf_esb_payload_t is defined as follows:
typedef struct
{
uint8_t length; /**< Length of the packet. Should be equal or less than
NRF_ESB_MAX_PAYLOAD_LENGTH. */
uint8_t pipe; /**< Pipe used for this payload. */
int8_t rssi; /**< RSSI for received packet. */
uint8_t noack; /**< Flag indicating that this packet will not be
acknowledged. */
uint8_t pid; /**< PID assigned during communication. */
uint8_t data[NRF_ESB_MAX_PAYLOAD_LENGTH]; /**< The payload data. */
} nrf_esb_payload_t;
Does the macro fill all the fields of this structure, if so, what will be the values of each field in this example?
Thanks,
