can't disable auto ACK?

[mr_creosote]

Hi, even if I set hal_nrf_enable_ack_payload(false) on the sender (and receiver), the receiver still sends back an ACK which i can detect in the NRF_ISR(). is this normal operation? this is confusing.

thanks,

do i have to use hal_nrf_write_tx_payload_noack (const uint8_t *tx_pload, uint8_t length) if i want to send with no ack? if so, what is the use of  hal_nrf_enable_ack_payload(false)? thanks!
