1 on error, and errno indicates the reason for failure. Value dependent on command class: NRF_F_GETFL - Value of file status flags. Parametersįd – The descriptor to set options on.Ĭmd – The command class for options. For a list of supported flags, refer to nrf_fcnt_flags. For a list of supported commands, refer to Descriptor manipulate API. Set or get file descriptor options or flags. int nrf_fcntl ( int fd, int cmd, int flags ) įunction for controlling file descriptor options.
In addition, the function shall return -1 and set the following errno: Modem was shut down. See POSIX.1-2017 article for normative description. Socket send and recv flags group nrf_socket_send_recv_flagsįunctions int nrf_socket ( int family, int type, int protocol ) This lets the modem stay in connected mode longer. Indicate that the socket is in active use by a server application. Indicate that the socket is in active use by a client application. This lets the modem exit connected mode more quickly after having received the data. Indicate that the application is expecting to receive just one data packet after the next call to send() or sendto(). This lets the modem exit connected mode more quickly after sending the data. Indicate that the application does not intend to send more data after the next call to send() or sendto(). This socket option applies immediately and lets the modem exit connected mode more quickly.
Indicate that the application does not intend to send more data. NRF_SO_TCP_SRV_SESSTIMEO Ĭonfigurable TCP server session timeout in minutes. NRF_SO_IPV6_ECHO_REPLY Įnable ICMPv6 echo reply. NRF_SO_IP_ECHO_REPLY Įnable ICMP echo reply. NRF_SO_SILENCE_ALL ĭisable ICMP echo replies on both IPv4 and IPv6. NRF_SO_RCVTIMEO īind a socket to network interface identified by a Packet Data Network ID. Read and clear socket error status (read only). NRF_EINVAL – len is too large to be a valid trace lengthĮnable reuse of server addresses NRF_SO_ERROR NRF_EINVAL – buf is NULL or an invalid trace buffer Len – Length of memory buffer as received in nrf_modem_os_trace_put
Parametersīuf – Pointer to the memory buffer as received in nrf_modem_os_trace_put Calling this function with incorrect values leads to undefined behavior. It is the application’s responsibility to call this function with the same parameter values as received in the nrf_modem_os_trace_put function.
Reasons for socker error 1 free#
The application shall call this function to let the modem library free the trace memory pointed to by buf. int nrf_modem_trace_processed_callback ( const uint8_t * buf, uint32_t len ) įunction to indicate that the application has completed the processing of a trace buffer. void nrf_modem_trace_irq_handler ( void ) Ĭall this function when handling the Trace IRQ. Void nrf_modem_application_irq_handler ( void ) Īpplication IRQ handler in the modem library.Ĭall this function when handling the Application IRQ. NRF_EPERM – The Modem library is not initialized.
Reasons for socker error 1 Offline#
The modem must be put into offline (CFUN=0) mode before shutting it down.
Resources reserved by the library in nrf_modem_platform.h are freed when the library is shutdown. Return valuesįalse – If the modem is uninitialized or in a fault state. NRF_EIO – IPC State fault or missing root digest.Ĭheck whether the modem is initialized. NRF_EINVAL – RPC control region size is incorrect. NRF_EPERM – The Modem library is already initialized. NRF_ENOMEM – Not enough shared memory for this operation. Init_params – Initialization parameters.Ī – positive value from Modem DFU when executing Modem firmware updates. To switch between DFU and normal modes, nrf_modem_shutdown() should be called in between. Library can alternatively be initialized in DFU mode, which means that all shared memory regions are now reserved for DFU operation, and therefore no other modem functionality can be used. In normal operation mode, the DFU functionality is disabled. Library has two operation modes, normal and DFU. Once initialized, the library uses the resources defined in nrf_modem_platform.h. Int nrf_modem_init ( const nrf_modem_init_params_t * init_params, enum nrf_modem_mode_t mode ) Return valuesĮmpty – string if version string is not defined. Return version string of the Modem library build. Remote procedure call library (nRF RPC)įunctions char * nrf_modem_build_version ( void ) .nrf_modem_init() return values for modem firmware updates.
