Hi,
I’m using an ESP32 with GSM and GPS module, as far I understand I should define the UART to assign the RT/TX pin; how I can define UART for both?
# Example configuration entry
uart:
rx_pin: D7
baud_rate: 9600
uart:
baud_rate: 9600
tx_pin: TX
rx_pin: RX
I didn’t find and example that can help me to understand how to assign more than one RX
regards
uart:
- id: uart_1
tx_pin: GPIO15
rx_pin: GPIO13
baud_rate: 9600
- id: uart_2
rx_pin: GPIO12
baud_rate: 9600
Oh boy!!!
So easy?!?! 
I have another question, if I setup
uart:
- id: uart_1
tx_pin: GPIO27
rx_pin: GPIO26
baud_rate: 9600
- id: uart_2
rx_pin: GPIO03
baud_rate: 9600
then I have to do something to connect the GPS and the GSM with the correct UART, right?
# Declare GPS module
gps:
latitude:
id: uart_1_latitude
name: "Latitude"
longitude:
id: uart_1_longitude
name: "Longitude"
altitude:
id: uart_1_altitude
name: "Altitude"
# GPS as time source
time:
- platform: gps
id: uart_1_time
uart_id:
can you help me with the indentation or do you have a full example
this produce this error

but i have to define the uart
Maybe put gps uart as first. And dont use uart_id for gps
You need test if gps will get the right one
Hi,
I managed to find the correct syntax
gps:
uart_id: uart_2
latitude:
now I’m trying to get the UART log using the info from Custom UART Text Sensor — ESPHome
but the sensor returns Unknown :(, I try to dig in a little bit
Test with only gps uart first and then add uart2
Gps uart may need to be the first
I think that gps component dont support uart_id yet
Thank you @nikito7, I’m following your suggestion
uart:

auto my_custom_sensor = new UartReadLineSensor(id(uart_2));
App.register_component(my_custom_sensor);
return {my_custom_sensor};

but the status is still unknown and I don’t get GPS data

You need good gps signal inside home
Hi,
I think that I’m doing something wrong. I placed the ESP outside, but I’m not getting any value from UART and I don’t get any GPS data 
I need to study a little bit more
You may need a sim, if it is a-gps like mobile…
Ahhh,
that’s can be the point
I connected the external GPS antenna
I had the impression that GPS and LTE are 2 different output. that’s why I’m trying GPIO03
You need to know what is gps pin
And you need good power supply
Just use one uart
I think rx is same
GPS is inside gsm
Any update? I’m looking into using the cellular option as well just for texts messages and such. Is this possible?
I found this Guide: LILYGO T-SIM7000G ESP32 (LTE, GPRS, GPS) | Random Nerd Tutorials, it sounds a good reference
based on that it seems that “This board only supports nano SIM cards. You need a SIM card for LTE and GPRS. However, if you only want to use GPS data, you don’t need a SIM card.”
this works:
