ThingstreamTransport implementation that communicates with a modem through a serial connection.
◆ MODEM_IGNORE_PLUS_CUSD2
#define MODEM_IGNORE_PLUS_CUSD2 (0x10) |
Some modems (e.g. Quectel UG96) return unsolicited "+CUSD: 2" when a USSD session is terminated by the server, but most modems return this for various USSD error conditions. By default the modem driver will treat an unsolicited "+CUSD: 2" as an error condition. Setting this flag causes unsolicited "+CUSD: 2" messages to be treated as informational only.
◆ MODEM_MERGE_USSD_SESSION_END
#define MODEM_MERGE_USSD_SESSION_END (0x4) |
The modem allows the AT+CUSD=2 command (which denotes the end of a USSD session) to be combined with the last USSD message.
This flag and MODEM_SPLIT_USSD_SESSION_END are mutually exclusive. Do not set both flags. If neither flag is set, then one of them will be chosen during initialisation.
◆ MODEM_SKIP_INIT
#define MODEM_SKIP_INIT (0x01) |
When this flag is set, the modem transport layer considers the modem hardware to be initialised already and will skip its own initialisation. This is needed when other features of the modem hardware are programmed by non-Thingstream software.
◆ MODEM_SPLIT_USSD_SESSION_END
#define MODEM_SPLIT_USSD_SESSION_END (0x8) |
The modem requires the AT+CUSD=2 command (which denotes the end of a USSD session) to be split from the last USSD message.
This flag and MODEM_MERGE_USSD_SESSION_END are mutually exclusive. Do not set both flags. If neither flag is set, then one of them will be chosen during initialisation.
◆ MODEM_STAGE_SHORTCODE
#define MODEM_STAGE_SHORTCODE (0x02) |
The modem will usually talk to the normal (or "live") Thingstream software server stack, but occasionally the Thingstream support team may request that you use the debugging rather than live stack. Setting this flag tells the modem transport layer to use the stage debugging stack.
◆ Thingstream_Modem_clearFplmnString
const char Thingstream_Modem_clearFplmnString[] |
|
extern |
◆ Thingstream_Modem_forceResetString
const char Thingstream_Modem_forceResetString[] |
|
extern |
See modem_reset_string.c
This string is used to reset the modem after a serious problem has been detected. Each entry in the string is terminated by "\n". If an entry starts with a "?" then the "?" is not passed to the modem, but any ERROR (or +CME ERROR:) produced will be ignored.
If the forced reset is successful it will be followed by the normal commands used to initialise the modem.
◆ Thingstream_Modem_informationString
const char Thingstream_Modem_informationString[] |
|
extern |
See modem_info_string.c
This string is used to obtain information from the modem once it has been initialised. Each entry in the string is terminated by "\n". If an entry starts with a "?" then the "?" is not passed to the modem, but any ERROR (or +CME ERROR:) produced will be ignored.
◆ Thingstream_Modem_initString
const char Thingstream_Modem_initString[] |
|
extern |
See modem_init_string.c
This string is used to initialise the modem. Each entry in the string is terminated by "\n". If an entry starts with a "?" then the "?" is not passed to the modem, but any ERROR (or +CME ERROR:) produced will be ignored. An entry of the form ~n inserts a delay of n ms into the sequence.
◆ Thingstream_Modem_readFplmnString
const char Thingstream_Modem_readFplmnString[] |
|
extern |
See modem_fplmn_string.c
This string is used to read the SIM's FPLMN list of barred operators. The SDK modem driver issues this string when it has been unable to register with an operator.
◆ Thingstream_Modem_ussdEndSessionString
const char Thingstream_Modem_ussdEndSessionString[] |
