I use a NRF52832 with SDK15.3 S332,
#define NRF_SDH_BLE_GAP_DATA_LENGTH 251
#define NRF_SDH_BLE_GATT_MAX_MTU_SIZE 247
When my device as a periph sending data to the central, it works well,but the wireshark shows that there are occasional irregular L2CAP Fragment.
Every time I send multiple 127B data queues, one or several of the 127B data will be split.
I can't find the reason,I also checked the data length, the CENTRAL REQ RX251 TX251,and my device also RSP RX251 TX251.
Although the data received by the host is correct, I am still confused about it.
