oups, initial bad branch push, This is a currently a draft PR, it needs more works. It is currently tested and developed on Lilygo T-SIM7600E. It use esp-modem, so it's I've been able to use There is some modem initialisation that need to be fixed. For now, it's better to start the device from a cold state (with no power). The PPPos data communication is done in CMUX mode, so it should be possible to send other AT command (gnss, gps, etc...) using the command channel (TODO). And I'm sot sure that pppos:

Did anyone here have any luck with this? modem:
use_address: <IP>I'm just getting an error when trying to use it |
|
For For the gps boot, the modem component use Let me know if using manually for `"(It shows [modem.nmea_uart:291] Invalid GNSS data in the log, but the satellites number didn't reset)", I will also fix that on the modem side: If GNSS invalid data is found (ie no fix/data), the nmea frame is not sent to the gps component, so the gps use the last known state. On invalid data, the modem should send an empty NMEA frame, so the gps component know that the gps is not fixed. |
If that's the same as the GNSS toggle, its not going to work. switch:
- platform: modem
gnss:
name: "${friendly_name} GNSS"
restore_mode: ALWAYS_ONI managed to create an automation that detects when GPS fails & auto reboots tho, which does get it working again. |

Been running great for the last few days 0 GPS disconnections and 0 crashes

This is great work! I also had to set I used |

@martivo thanks for testing!
I'm not actively developing the component for the moment, but will be back in few month. |

I did some further testing. I hope these logs are useful. I attached full logs, but tried to point out the differences here. With Full log cmux_enabled.txt When I use I tried both OTA configurations: Here is the log when I enable the Full log wifi_enabled.txt If you need more logs or extra information about the configuration then let me know. I would like to help as this would make my setups so much easier. No need for a separate LTE router with this. Normal boot log with wifi and cmux disabled. normal_boot.txt |
The only way to enable OTA updates through the ESPHome dashboard atm is by configuring the WiFi component (just for the AP) and adding Take a look at what I did on https://github.com/ShonP40/Car-Assistant |

@martivo , I've bumped esp_modem from 1.4.0 to 1.4.2 . This might fix some bug related to For OTA, I haven't made some test for a while, but it should works with http_request platform: OTA can't be used in the legacy or web_server mode, because the modem has a private IP, and can't be reached from the internet unless you use a wiregard VPN as @ShonP40.

I think something is now broken. It will always give me this error without changing the config. I still use the same external_components. When i remove it and the modem block it is compiling.
@oarcher Thanks! I will give it a try. I already have wireguard working. However I am unable to try anything since I am now unable to compile it after the latest changes.
@ShonP40 Thanks, I will try to set it to AP mode. |

@martivo , hare you using lastest dev esphome branch ? as @SeByDocKy noticed in discord, some changes has been introduced because of #11704 |
Hi, no I was using regular release until now. Ill try "dev" and see how it goes. However I now noticed that just adding the |
Do you mean you had both an internet WAN IP address and be able to do OTA over local WiFi ? |
No, I put the wireguard VPN device ip as the |
@oarcher, when I use the Unfortunately the The This update was done over LTE and Wireguard. On a side note: I noticed that esphome dashboard will ping/pull the address all the time and creates quite a lot of traffic. This seems to happen even when the dashboard is not opened in the browser. If your LTE has very limited data capacity, then change |

What does this implement/fix?
This implement pppos tcp/ip for esp32, on lte/4G networks. It conflict with

The modem component use esp_modem from espressif, using simple_cmux_client example, and inspired from esphome ethernet component.
