STM32WB55 (server) When I notify 15bytes, the interval is about 7.5ms. When I notify 120bytes, the interval is about 30ms. Please what is causing this and how can I change these intervals？

Thank you for your kind help. I have solved this problem, mainly with this command：hci_le_set_data_length(BleApplicationContext.BleApplicationContext_legacy.connectionHandle,251,2120);
Next time I will make fewer invalid posts, because there is too little information about stm32wb55, I can only come to stcommunity to find someone to discuss.:face_with_tears_of_joy:
