Antronics Ltd provides consultancy and embedded firmware development services on a contract basis, with particular experience in GSM & M2M applications:
Clients have ranged from big-names like BT to small, local start-ups:
Key competence is interfacing, control, and communication with embedded microcontrollers.
If you develop electronic devices, and need some help with the software development, then give us a call.
Or if you have an existing device and need to add connectivity - such as GSM, GPRS, Ethernet, etc - for remote monitoring or control, we may be able to assist.
We may also be able to assist with relatively "low-level" PC software - especially involving serial communications - such as is often required during the development & testing of embedded devices.
