Is there any suggested "TXIDLE Time" for nRF52840 transmit sequence?

OA_Litum

Hi everyone,

As I mentioned in the subject, how many time do we wait for sending Start and Disable commands after Ready and End interrupts in transmit sequence of nRF52840?

We do not prefer to use shortcuts to avoid delays. We are using 2.4GHz proprietary 2Mbps mode.

Thank you in advance

Regards

    Hi,

    Thank you for your reply. But we do not want to use shorts. We want to receive interrupts and send back the related command. We want to use this transmit sequence. So I want to learn that how long is the TXIDLE state? Can I send the START command immediately after receiving the READY interrupt? Or shall I wait for any time to response?

    It is as long as you define it to be. If you stay in this state for 200 us before doing something that triggers a new state change, then its 200 us long.

     Yes, or you can use shorts to do this for you so you do not have to involve the cpu in the process.

     

    Kind regards,
