Hi,
I am using 2 nRF52832, one for ESB Tx and one for ESB Rx used to send payload through UART using SDK11.
Tx board is used has a low power transmitter which transmit data on power up and shutdown after transmission as succeeded using event flag NRF_ESB_EVENT_TX_SUCCESS.
Rx board is used to retrieve those intermittent payload with event flag NRF_ESB_EVENT_RX_RECEIVED. Once a payload is received, it is send to uart via app_uart_put. This works great. The problems we have is that we require a call to nrf_esb_flush_rx after receiving the first payload, otherwise no payload will ever be received again. With the flush_rx call, the Rx works forever without trouble. In some rare occasion, we will receive 2 payload, back-to-back (normal use-case). Using the nrf_esb_flush_rx, the second payload is always drop from the rx_fifo. Why is the nrf_esb_flush_rx require ?
As a starting point, we used the esb_low_power_prx/ptx example and stripping out all the LEDs/gpio part. Prior to that, pressing a button didn't required the nrf_esb_flush_rx to works.
Attached, is the simplex prx code to reproduce the problem. prx.cpp ptx.cpp
Any help would be appreciated.
