PSoC 4 MCU

We use Psoc4 CY8C4247QI-BLE483 as peripheral device and Android device as central device. After successful connection, data is transferred from the peripheral device to the central device using notification mode. The problem is that the transmission becomes very unstable when the data frequency exceeds 100Hz (send notification once at 10ms). After the data has been successfully transmitted for a period of time, the transmission fails (no data transmitted to the central device, but the connection state was still successful). Each successful data transmission duration is random, sometimes more than ten seconds, sometimes a few minutes, the longest time is about 10 minutes. If the frequency of notification is set to 50Hz (send notification 20ms once), no problem will occur and the data transmission can be maintained all the time. Have a friend to encounter similar problem, be how to solve? Is it a BLE bug?

It seems to be a duplicate thread with PSOC4 BLE传输频率大于100Hz时会不稳定

We can discuss about the problem in the other thread.
