Radio Interface Layer - RIL¶

Header File¶

include/ril/ril.h

Functions¶

int ril_send_atcommand(const char *cmd, atrsp_callback_f cb, void *arg, unsigned int timeout, int wait)¶

Execute and AT command. This function implements sending AT command with the result being returned synchronously. The response of the AT command will be reported to the callback function

Return

RIL return code ril_rc_e

Parameters

cmd: [in] AT command string
cb: [in] processing callback function atrsp_callback_f
arg: [in] User argument passed to callback function
timeout: [in] Timeout for command execution
wait: [in] Wait for RIL to be available (TRUE) or not (FALSE). If wait is false, function returns immideatly if RIL is unavailable. If true function will wait for RIL availability until timeout occurs.

int ril_write_data(const void *data, int len)¶

Send data to RIL core

Return

On success, this function returns actual length of data written, negative code on error

Parameters

data: [in] Pointer to data to be sent
len: [in] Length of data

int ril_urc_attach(const char *keyword, urc_handler_f callback)¶

Attach URC to RIL core

Return

0 on success, negative value on error

Parameters

keyword: [in] URC Keyword
callback: [in] URC handler function

int ril_urc_detach(const char *keyword)¶

int ril_lock(int timeout)¶

Get exclusive access to Radio interface layer. This lock is only an advisory lock for RIL.

Note

ril_lock() and ril_unlock() should be called from same task

Return
