@qnixAVA - sorry for my lack of knowledge, but how would I go about using that code ?

Thanks so much, I have included it and it compiles with no errors, but how do I use it: ``` sim7600: on_sms_received: - logger.log: format: "Received '%s' from %s" args:...

Have tried to figure it out, but compile fails with `Component not found: sim7600.`: ``` esphome: includes: - sim7600/sim7600.h custom_component: - lambda: |- auto sim7600 = new sim7600(); App.register_component(sim7600); return...

thanks so much that worked :-)

Well it seems that I can receive SMS but I cannot send and are not sure where to start debugging: ``` [10:00:05][D][uart_debug:158]: >>> "\x1AAT+CSCS=\"GSM\"\r\n" [10:00:05][D][uart_debug:158]: > "AT+CMGS=\"+XXXXXXXXXX\"\r\n" [10:00:05][I][sim7600:343]: Sending to...

I have the same problem, every time the modem is powered on it gets a brownout. I have fully charged 18650 3200mah battery and alternatively supplying power via VBAT pin...

Yes this is a problem. The power Pin must be set high at boot time, if you set it after boot you will get immediate brownout. And this means that...

Is there a solution to this ? Whenever Power Pin is set high (GPIO12) the device brownouts no matter whether connected to battery or USB. Adding capacitors across the supply...

I am using the T-A7608, it was delivered a week ago. Yes, as soon as you enable GPIO12 high, it will force a brownout and device reset. This happens every...
