@panicjp Have you tried using the [`_Cellular_TimeoutAtcmdDataRecvRequestWithCallback`](https://github.com/FreeRTOS/FreeRTOS-Cellular-Interface/blob/main/source/include/common/cellular_common.h#L557) API? You can see the example usage of that API in the implementation of `Cellular_SocketRecv` API for BG96: [FreeRTOS-Cellular-Interface/modules/bg96/cellular\_bg96\_api.c at e173977bc8548d8720b3adda566a609910cd8bcf · FreeRTOS/FreeRTOS-Cellular-Interface · GitHub](https://github.com/FreeRTOS/FreeRTOS-Cellular-Interface/blob/e173977bc8548d8720b3adda566a609910cd8bcf/modules/bg96/cellular_bg96_api.c#L2506) The `pktDataPrefixCallback` callback function is required to indicate the data start address and data length, along with returning `CELLULAR_PKT_STATUS_SIZE_MISMATCH` until required raw data bytes are received. You can refer a similar thread [here](https://forums.freertos.org/t/cellular-library-need-help-implementing-raw-binary-recv-data/17304) for more data. --- _[View the full topic](https://forums.freertos.org/t/cellular-interface-handling-at-qfread-responses-and-binary-data-in-freertos-cellular-interface-for-bg96-modem/21877)._
