****************

have other advices for this ? about number of data frames in transmit queue?

i found transmit queue in Coprocessor ,to add service multi devices data request?

/* maximum number of data frames in transmit queue */

#ifndef MAC_CFG_TX_DATA_MAX
#define MAC_CFG_TX_DATA_MAX         4// 2
#endif

mac_cfg.c file

txDataMax     Maximum number of data frames queued in the transmit data queue.     1–255     2
txMax     Maximum number of frames of all types queued in the transmit data queue.     1–255     5
rxMax     Maximum number of frames queued in the receive data queue.     1–255     2
dataIndOffset     Allocate additional bytes in the data indication for application-defined headers.     0–127     0
appPendingQueue     When TRUE, registered callback of type ApiMac_pollIndFp_t will be made to the application when a data request command frame is received from another device.     TRUE or FALSE     FALSE

Thank you for considering my request.
