Background: SDK 16.0.0, SoftDevice 7.0.1, 1 ble_central connected 6 ble_peripheral, Send an instruction to 6 ble_peripherals every 50 milliseconds, at the same time, the ble_peripheral returns the response data to the ble_central . An error will be reported after running for a period of time, the error code is as follows. The screenshot below is the error generated within 15 hours, 11times / 15 hours.
