IOT based on Sonoff RF Bridge 433 Mhz + GSM/GPRS modem

Hi, I hope you are doing well. I have expertise in RF,WiFi and GSM based embedded projects. I have reviewed your project details and seen the schematic of Sonoff RF Module. This is MCU used EFM8BB10F4G in that module. I think its better if we can do the work from scratch. Looking Forward for your response. Khawaja
