Hi Freelancers, We are considering using an Android phones to log data from devices on RS485 Modbus RTU networks. Each network will have a RS485/Bluetooth adaptor fitted to enable the phone to communicate via Bluetooth. There is an app called Modbus Master Pro which does this communicating and sets up which registers you wish to monitor. However, we wish to use a web interface to set up the monitoring and also allow modbus registers to be changed remotely (e.g to turn outputs on/off). All logged data needs to be stored in a database and then some of this data will need to be automatically sent to an ftp server in an HML file (transfer interval is normally once/day). Similarly some data may need to be automatically emailed in a csv file. The main types of device that will be monitored are flowmeters, we need to get flow and volume data from them every 15minutes. Then store this data and send some of it to a regulatory authority. Thank you for considering.

In fact, Nokia, has funded one of my development projects for an app targeted at their Ovi Store --- an emergency hotline and geo-tracking app on Symbian. Earlier this year, I worked with a my team to develop a custom reusable CMS for an Australian creative agency. With the same team, I developed an enterprise ordering & delivery tracking application on both the web and mobile. 2 months ago, we finished developing 2 apps on Android --- a social geo-messaging app, and a social geo-gaming app --- for a US customer in behalf of another software dev't outsourcing company in Hawaii.
