#####Code explanation
The main file that is needed to run is receiveSendSMS.py. The code's explanation can be found in the file itself. This file is responsible to receive SMS, process them and take necessary actions like changing LED colours, sending feedback SMS to healthworker. This also saves the SMS request in file "records".
Another main script, phantLoggerGSM.py which runs at night time and uploads all the new entries received during the day which are saved in "records" file. The explanations for this file can also be found in that file only.
#####LED indicators In the initial prototype, green is a normal indication. Red indicates an unanswered stock shortage and request, and yellow indicates that the order is available at the CHC. When the status of a sub-center is changed to yellow, an automated SMS will be sent to update the sub-center worker.
