Hi,
Maybe you have 50ms connection interval for the BLE link.
You should try to reduce the connection interval.
Thank you for your answer~! How can I change that interval time???
my gatt define is below
Your defines looks correct.
I recommend checking what parameters the link is actually using, by using the nRF Sniffer to take a on-air sniffer trace. https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Sniffer-for-Bluetooth-LE
