$250-750 USD

Paid on delivery
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 and Android app modification (modifying existing app) and upload the new softwawre to Android and iOS platforms (using our existing account)
