thanks for your reply, According to your suggestion, I modified the code as follows and found no problem with 0x13,

do
{
err_code = ble_nus_data_send(&m_nus, data_array, &len, m_conn_handle);
if ((err_code != NRF_ERROR_INVALID_STATE) &&
(err_code != NRF_ERROR_RESOURCES) &&
(err_code != NRF_SUCCESS) &&
(err_code != NRF_ERROR_BUSY) &&
(err_code != NRF_ERROR_NOT_FOUND))
{
APP_ERROR_CHECK(err_code);
}
} while (err_code == NRF_ERROR_BUSY || err_code == NRF_ERROR_RESOURCES);

Regards,

Hi,

Regarding the log, the error 0x13 seems from sd_ble_gattc_write() in queue_process() request_process(). See my explanation in this thread.

                NRF_LOG_DEBUG("GATTC Write Request");
                err_code = sd_ble_gattc_write(conn_handle,
                                              &ble_req.params.gattc_write);

Please try to patch the module provided by Vidar in this post and see if you get the same result.

Regards,
Amanda

#define	NRF_ERROR_RESOURCES (NRF_ERROR_BASE_NUM + 19)
	Not enough resources for operation.

But I don't know what kind of resource shortage is。The smaller the time interval between sending data, the more likely this problem is。

sender code:

do
{
ret_val = ble_nus_c_string_send(&m_ble_nus_c, tmp, len);
if ( (ret_val != NRF_ERROR_INVALID_STATE) && (ret_val != NRF_ERROR_RESOURCES) )
{
APP_ERROR_CHECK(ret_val);
}
} while (ret_val == NRF_ERROR_RESOURCES);

Hi,

The error 0x13 is 19 in decimal and that means NRF_ERROR_RESOURCES. See Vidar's answer in this post.

Hi John,

You should debug and find the error that comes from which function. Set NRF_LOG_DEFAULT_LEVEL to 4 in the sdk_config.h to output logs from NRF_LOG_DEBUG macro. Please provide the debug log.

Hi Amanda,

I used ble_app_uart_c and ble_app_uart, and modify the example for multilink. My ble_app_uart_c connect to STM32 use UART, CMD is from STM32 MCU, 50ms is controlled by STM32.

Hi John,

Are you using ble_app_uart_c and ble_app_uart? Did you modify the example? Does it also happen to only one ble_peripheral?

Could you check the error come from which request_err_code_handle in the project?

Maybe this and this post can help. If not, please compile with debug mode to provide the debug log.
