pyupm_gprs module

class pyupm_gprs.GPRS(uart=0)

Bases: object

API for the GPRS Module.

ID: gprs

Name: General Packet Radio Service ( GPRS) Module

Other Names: Grove GPRS Module

Category: wifi

Manufacturer: seeed

Connection: uart

Link:http://www.seeedstudio.com/wiki/GPRS_Shield_V2.0 The driver was tested with the GPRS Module, V2. It’s a GSM GPRS module based on the SIM900. This module uses a standard ‘AT’ command set. See the datasheet for a full list of available commands and their possible responses:

It is connected via a UART at 19200 baud.

C++ includes: gprs.hpp

dataAvailable(millis)

bool dataAvailable(unsigned int millis)

Checks to see if there is data available for reading

millis: Number of milliseconds to wait; 0 means no waiting

true if there is data available for reading

readData(buffer, len)

int readData(char *buffer, unsigned int len)

Reads any available data into a user-supplied buffer. Note: the call blocks until data is available for reading. Use dataAvailable() to determine whether there is data available beforehand, to avoid blocking.

buffer: Buffer to hold the data read

len: Length of the buffer

Number of bytes read

readDataStr(len)

std::string readDataStr(int len)

Reads any available data and returns it in a std::string. Note: the call blocks until data is available for reading. Use dataAvailable() to determine whether there is data available beforehand, to avoid blocking.

len: Maximum length of the data to be returned

Number of bytes read

setBaudRate(baud=19200)

int setBaudRate(int baud=19200)

Sets the baud rate for the device. The default is 19200.

baud: Desired baud rate.

true if successful

writeData(buffer, len)

int writeData(char *buffer, unsigned len)

Writes the data in the buffer to the device. If you are writing a command, be sure to terminate it with a carriage return ()

buffer: Buffer to hold the data to write

len: Length of the buffer

Number of bytes written

writeDataStr(data)

int writeDataStr(std::string data)

Writes the std:string data to the device. If you are writing a command, be sure to terminate it with a carriage return ()

data: Buffer to write to the device

Number of bytes written
