When I use the uart to transparently transmit, there is no problem at around 4k/s. When I increase the transparent transmission rate, there will be NRF_ERROR_SVC_HANDLER_MISSING this error in the APP_UART_COMMUNICATION_ERROR event.
What is the reason, I have been unable to find the reason, if you want a higher transmission rate, what should I do, I do not want to use flow control, dma is not a better choice?
Hi,
I believe that the error is really NRF_UARTE_ERROR_OVERRUN_MASK. Please check this by taking a look at the value of app_uart_evt_t::error_communication when the error occurs. As indicated here, the value is 1 when the UART is overrun.
Please enable the EasyDMA if you have not already done that, and see if it improves the situation.
but i find this error only 1kb/s this sometimes , which is strange, what happen , is this error code of myself?
What do you have at line 798 and 797 in main.c ?
this is APP_UART_COMMUNICATION_ERROR
I want to know why this is not the case with the NRF52810, and this is the case with the NRF52832.
Make sure that you have UART_EASY_DMA_SUPPORT set to 1 in sdk_config.h. You can also try to increase the RX/RX buffers, and see if that helps (UART_TX_BUF_SIZE/ UART_RX_BUF_SIZE). Slightly increasing the UART IRQ priority might also help, try setting UART_DEFAULT_CONFIG_IRQ_PRIORITY in sdk_config.h to 6.

I didn't turn on UART_EASY_DMA_SUPPORT =1 because I have tried to turn it on, but turning it on will cause the power consumption to be upgraded to about 2mA. Compared with the 52810 power consumption is too high. As mentioned here, the 52810 does not appear in the case of not turning on UART_EASY_DMA_SUPPORT. Error, I set the uar priority to 6 buffers to 512. The effect is improved, but this problem still occurs. I am now trying a higher uart priority.https://devzone.nordicsemi.com/f/nordic-q-a/36342/uart0_config_use_easy_dma-1-lead-hight-consumption
UART_EASY_DMA_SUPPORT =1 Isn't really turning on DMA, but what is this used? I tried to turn on UART_EASY_DMA_SUPPORT =1 to avoid this error, but why it leads to such high power consumption, we are going to produce the product, with the same series. The 52810 is not normal compared to this
I gradually increased the rx buffer 1024 tx buffer512 uart UART_DEFAULT_CONFIG_IRQ_PRIORITY to 2 The result did not improve,
My original code is on NRF52810. This problem does not occur, but I have this problem when I ported to 52832.
How does your makefile look like ?
Did you remove DNRF52810_XXAA, and added DNRF52832_XXAA ?
Did you remove DDEVELOP_IN_NRF52832?
Was the nRF52810 a QFN48, QFN32 or WLCSP varaint? The pin assignments might be different here compared to a nRF52832 QFN48.
Have you checked that TX and RX are connected to the correct pins?

I used the logic code of sdk13 52810, then modified the logic code on the ble_uart_peripheral routine of sdk14.2, and then I encountered this problem. I don't think this has anything to do with the makefile.
