Hi,
I am developing an application with to 7 transmitters (peripheral) and one receiver (central = nrf52DK), all NRF52832.
I have 1 question and one problem to solved:
Question: all receiver are sending collected data's at the same time at 20 - 40Hz frequency (in testing). ESB transmission is set to
tx_payload.noack = true;
to prevent central overload and crash.
One of the transmitter is connected to the nrf52DK in order to follow nrf_log in debug mode. When transmitting the data,
"TX FAILED EVENT"are log from time to time. Since noack is set to true, I don't understand why. This does not seems to cause an issue.
Problem : I am using the nrf52DK as a central. Through the computer, i am sending to the central a command is relay to each active peripheral. For exemple, key = 4 start data collection at 40 Hz, z will reset some parameter. This is working fine most of the time, about 9 over 10 time. Sometime if press key z , the receiver will get the command z but also the previous one , 4. It seem that at the central, the TX buffer was not erase correctly, it could be something else.
using the following code in the central
(void) nrf_esb_flush_tx(); (void) nrf_esb_start_tx();
before sending new command does not help.
Any suggestion would be appreciate.
