Can we update Quectel UC20 module like a general microcontroller to get sensor data via I2C and send it as an sms? I have UC20 evb.
I think what you mean is that take the UC20 as MCU and you would develop APP on UC20.
As far as I know it don’t support.
If you must that feature, I think it is better to try Quectel OpenSolution.
QuecOpen might be the best choice.
Do you have an external MCU?
You can only make the MCU communicate with the Quectel modem via UART or USB.
Quectel provide the AT commands for you,
I have an NodeMCU-32s (esp-wroom-32) and also NodeMCU-12E (ESP8266). I just found out that I have to use RS232 to TTL converter in order to establish communication between my MCU and UC20 attached to EVB. It will work right?
yeah yeah! I got AT Commands.
Yes.
Make sure the the MCU can communicate with the UC20 via uart.
Sir one more small doubt… Can I use 4G/5G sim cards for UC20 Module?
Yes. If the SIM card support 3G/4G network,
