Initially I'm seeking consulting advice about the feasibility of connecting a GSM/GPRS modem board to a Sonoff RF Bridge 433Mhz ([login to view URL]). The GSM/GPRS modem will be used to connect to the internet and send MQTT messages. It would be helpful if you have other/better suggestions how I can run Espurina firmware ([login to view URL]) using GSM/GPRS for the internet connection. What I need: * Advice about whether it's possible to connect GSM/GPRS modem board to a Sonoff RF Bridge. * The best GSM/GPRS board to use. * How it would be connected.

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
