My team and I have plenty of experience in developing electronic products involving Bluetooth 4.0, Wi-Fi and NFC. We have a BLE solution that connects a home appliance to an Android app in a mobile phone. The apps can retrieve and send data to the home appliance. We have a similar solution for a BLE wrist belt. The belt has multiple sensors, LCD and lithium re-chargeable battery. This belt can be connected to iPhone using Apple’s ANCS. We also have a NFC reader solution that can read/write on NFC tag card, send the data to PC. It can also be connected to mobile phone using BLE or even Cloud through Wi-Fi. We are using the AS3911 chip from AMS and our main cpu is an ARM processor. This ARM processor can also read SD card and play audio. This is for consumer and games application we developed two years ago. We developed a Wi-Fi module for a client two years ago. A client put it into his home appliance. Our Wi-Fi module allows the home appliance to be connected to a remote cloud server through the end-user's home Wi-Fi router. The end-user can use his mobile phone's apps to access cloud to control the home appliance. Thus he can turn on/off the appliance as well as retrieving data (such as the home temperature) from anywhere in the world. This product sells tens of thousands of unit in the last 24 months. In addition to making firmware, iOS/Android apps, we also have hardware engineers and sourcing specialist that can buy all the necessary components, make full-function hardware prototypes and even get certification for you. We work closely with laboratory and help our clients get FCC, CE and UL certifications. I'm an electrical and electronic engineer and owner of Hiswill Electronics Limited. We are a Hong Kong product development and sourcing company with an engineering team in Shenzhen China. We have been in the electronic business providing sourcing and engineering services to our US and Europea
