I have a data logger prototype. It records data through sensors and send those every 5 seconds to our AWS server. Data is being sent via a 3G/4G connection (through a SIMCOM 5320E). The data logger setup is made via bluetooth connector using and Android or iOS smartphone. So far, the menu only allows us to setup the 3G/4G APN. I need to be able to add the SIM pin code, username and password. In short I need: 1) ISP STM32 microcontroller programming (modifying an existing program) with step-by-step instructions on how to load the new firmware 2) iOS + Android program modification (modifying existing app) and upload the new software to Android and iOS platforms (using our existing account)
