# sim-access

A Python module for managing SIM modules

## Setup

The setup is:

- A serial sim module SIM7500A (SIM800L is supported too).

- A USB to serial module connecting my computer with SIM7500A. 

The reason I am using a USB to Serial module is because I always want to make things easier to integrate with different setups. I hate connecting different GPIO wires with the SIM module and this is not sexy at all. With a USB to Serial module. It can be easier to plug and unplug to your systems.

 

## Coding

### Texts and Calls

To receive SMS and calls, you need to write a class from base class SIMModuleBase. There are two method you need to implement. **on_sms()** and **on_call()**. Here is one example.

```python

class MySIM(SIMModuleBase):

    def on_sms(self, number, content):

        print('Text from: {0}, Content: \"{1}\"'.format(number, content))

    def on_call(self, number):

        print('Got phone call from {0}'.format(number))

        time.sleep(5)

        self.call_hangup()

    def on_call_missed(self, number):

        ''' This function is not working for SIM800

        '''

        self.sms_send(number, 'Sorry, I missed your call!')

if __name__ == '__main__':

    MySIM().mainloop()

```

You can detach the mainloop thread

``` python

    a.mainloop(True)

```

You can manage the loop yourself

``` python

    while True:

        # do something 1 ...

        a.loop_once()

        # do something 2 ...

```

### GPS

You can also get your GPS locations, date and time using method **gps_location_date_time**

``` python

    class MySIM(SIMModuleBase):

        ...

    

    sim = MySIM()

    ((mylong, mylat), mydate, mytime) = sim.gps_location_date_time('')

    print('Longitude: {0}\nLatitude: {1}\nDate: {2}\nTime: {3}\n'.format(mylong, mylat, mydate, mytime))

```

Whenever you received an SMS, **on_sms()** willl be called. If you receive a phone call, **on_call()** will be called. Please note that **on_call()** could be called multiple times during a phone call.

There is no implemenation of answering the phone call right now. The SIM module I bought does not support answering phone calls.

## Implementation

Internally, I use a thread to monitor incoming texts and calls.
