PLEASE HELP nRF2401A!!

I successfully got both modules to transmit and receive, but when I try to switch to the other mode (from transmit to receiver or receive to transmit)

nothing works.

I want to switch device from RX mode to TX mode in order to send an ACK back to the sender. I know the newer modules will automatically do this but I got stuck with 4 older modules and I would like to use them.

Do I have to send entire config string or just the first bit (LSB, RXEN)

I am using one of the older modules with the nrF2401A.

I tried 200uS delay, 1mS delay and 10mS delay (according to the datasheet) and I am not having any luck.

CAN ANYONE PLEASE HELP??

I have been trying to do this for DAYS with no luck!!

In theory only the 1bit is needed, but I always send the whole set.

I’d say you’ve got a problem in delay before changing mode. Also, are you sure you’re waiting enough, AFTER the bytes have been transmitted? (I mean, after you send the bytes to the 2401, and then enough time for it to transmit them)
