Nano 33 BLE (Sense) one Central and multiple Peripherals-MTU

[tangtangdn]

Hi, I am trying to connect one Nano 33 BLE (Sense) (Central) with another two (Peripherals). When the 18 bytes of data are transmitted as a data packet, it works. However, when 198 bytes of data are transmitted as a data packet, it only received the data from one peripheral and fail to receive from two peripherals simultaneously. May I ask whether the default MTU is set to 23 bytes? But the peripheral can successfully send 198 bytes in a data packet when only one peripheral is connected to the central device. How to increase the MTU? Or should the connection interval be set with BLE.setConnectionInterval(min_interval, max_interval);? Many thanks.
