development dual mode(ble and 2.4G) with nrf 52810

[zcj]

Dear Sir,

please do me a favor to reply on my following question.

our project is a keyboard which we expect can work on both ble and 2.4G. we will use other brand of of 2.4G chips on the usb dongle side, thus, we need to modify and have our own protocols. currently, the other brand 2.4G has a packet format of no S0, no S1 and no length fields,

my question is, can we use nordick SDK's ESB example as a base for our product development, ie can we modify s0, s1 and length as zero bits in the ESB example code?

static void update_rf_payload_format_esb_dpl(uint32_t payload_length)
{
#if (NRF_ESB_MAX_PAYLOAD_LENGTH <= 32)
// Using 6 bits for length
NRF_RADIO->PCNF0 = (0 << RADIO_PCNF0_S0LEN_Pos) |
(6 << RADIO_PCNF0_LFLEN_Pos) |
(3 << RADIO_PCNF0_S1LEN_Pos) ;
#else

above code the original config

Sure, there are also \examples\peripheral\radio that can be used for reference. In that case all S0 and S1 are set to 0.

Best regards,
Kenneth

Hi Kenneth,

many thanks for your prompt reply. sorry to ask you clarify again, did you mean 0 << RADIO_PCNF0_LFLEN_Pos) is also ok ?

[Kenneth]

Yes.

/* These are set to zero as ShockBurst packets don't have corresponding fields. */
#define PACKET_S1_FIELD_SIZE      (0UL)  /**< Packet S1 field size in bits. */
#define PACKET_S0_FIELD_SIZE      (0UL)  /**< Packet S0 field size in bits. */
#define PACKET_LENGTH_FIELD_SIZE  (0UL)  /**< Packet length field size in bits. */

many thanks for your help. in that case, ESB will be suitable to my project usage.
