@hwhack It seems The SIM7600G-H R2 only comes in this big package with this battery already - is there one without that battery - where did you order it?
The slow sped is consistent with the baud rate form the ESp32 to the modem- 115200 bits per second = 11520 bytes per second - so 120kB file at 11.5kB per sec would take 10.41 sec plus some overhead. Try a faster UART baud rate.
Thank you for your comments. When I was working on this project, I tested by changing the baud rate between LTE modems, but there was no change in transfer speed. Maybe I'm missing something else?
Did you check if you used LTE and what LTE-mode the module was in? UMTS R99 speed: 384 kbps DL/UL HSPA+: 5.76 Mbps(UL), 42 Mbps(DL) HSDPA/HSUPA: 2.2 Mbps(UL), 2.8 Mbps(DL) LTE CAT 1: 10 Mbps(DL) 5 Mbps(UL) LTE-FDD CAT4 ：150 Mbps (DL)，50 Mbps (UL) LTE-TDD CAT4 ：130 Mbps (DL)，35 Mbps (UL)@@ThatProject Did you use baudrate up to max? Baud rate: 300bps to 4Mbps
Could you kindly explain how to update the firmware of an ESP32 using an LTE Modem, specifically the SIM7600G-H model? I'm interested in the process, including any required hardware setup, software configuration, and steps to ensure a reliable update. Additionally, if there are any particular best practices or precautions to consider, I'd appreciate your insights. Thank you!
Hi is a similar approach to upload images on server using sim800/900 series possible over 2G network? As I get iot enabled 2G SIM cards for dirt cheap prices!
Can I use this module as 4G WiFi hotspot router to access internet where WiFi is not available by uploading code to ESP32 to set this module to work as 4G WiFi hotspot using 4G data SIM. Please confirm. Thanks & kind regards.
If you have a personal server in your local server, you can access it from your phone via WiFi. The purpose of this project is to demonstrate updating to a cloud server using GSM within an MCU environment.
Is there any way to modify your code to have the t-simcam board go into deep hibernation and only wake every 60 minutes to take a photo, send it over LTE to a server, then go back to deep hibernation?
Yes, it seems possible enough. After taking and uploading a picture, you can switch to Deep Sleep mode using the following function. void deep_sleep(int seconds) { esp_sleep_enable_timer_wakeup(seconds * uS_TO_S_FACTOR); // uS_TO_S_FACTOR 1000000ULL // Conversion factor for micro seconds to seconds esp_deep_sleep_start(); }
What phone did you select in order to order the sim card? It seems a phone needs to be selected - no option to enter simcom as what the sim card is for.
unfortunately now there is not option to choose a data only plan without first selecting a phone of some sort. Do you by chance have a new link that would get me to the data-only plan without selecting a phone? The link you provided for the referral code just goes to a main landing page.
@@timvandusen4192 In my case, I think I was able to apply for a data-only SIM because I was already using Google Fi. Would you please check this out? I'm not sure.
I found out that all nano-SIM cards are the same, so I just found a phone that takes the nano-SIM and selected that as the one. Anxious to see how it works. BTW, awesome video! Very much appreciate you taking the time and effort to be so thorough.

@@ThatProjectthank you for the answer. I check the firewall rules (of my google cloud VM) and I didn't create a firewall rules. Instead I created a firewall policy. Now it works fantastic. Sorry for my comment. Maybe someone else has the same error :)
This is not possible with my current settings. Please let me have more drill down for the LTE connection. This is my first cellular project so I need to do more to use 100%.
We hope so, because nobody else seems to offer a solution to send video over 4G with esp32 and sim7000. Your 4W-car with esp32 cam, controlled by 4G in 2024 please :-) thx in advance.
@@MaximeROBERT-rl6hd In order to send any data to the server, at least TCP communication is required. HTTP is just a layer on top of TCP. Anyway, you must use TCP (HTTP) to upload images to the server.
@@ThatProject Hi, I already tried to do this with an Esp-cam without success. I would like to take a lot of pictures in one day and send them to a Google Drive folder to make a time-lapse video. Can you make such project please? Thank you very much

오랜만에 채널 들어왔는데 영상 퀄리티랑 프로젝트 퀄리티가 완전 업그레이드 되었네요. 잘 보고 갑니다. 언제 한 번 뵙고 싶네요!
The SIM7600G-H is EOL. The SIM7600G-H R2 is the recommended modual to use. It costs ~$50 usd.
Thank you for good information.
@hwhack do you have a link to the SIM7600-H R2?

Also check: Walter - ESP32-S3 5G IoT module - looks like they will be available soon - what you think of the specs?
Any link for this?
@@ThatProject how to post links here? If you google it it should be first result.
Can you also make a video about the T-SIM7600 R2 and a solar cell and a camera (e.g. OSV5640, OV2640) with live streaming?
Maybe. Let me think about that project.
Sooo cool thank you! I am a noob, did you make this board from scratch?
Thank you. I used products from LilyGo for this project.

As I get iot enabled 2G SIM cards for dirt cheap prices!
I don't know if you can use the same way to update images over a 2G network but it's worth trying.
Sim7600 has USB 2.0 (USB device mode only). Do you think it is possible to interface the module with MCU via USB & achieve high data rate ?
If you control directly using AT mode, it seems that you can use it like a modem. Have a look at this www.waveshare.com/wiki/SIM7600E-H_4G_HAT

This is an absolutely amazing project, but this board is soo expensive. 😢
can we use esp32 cam board with sim800l module if yes we need tutorial sir love from india
What is Google server using as OS? Linux? Or does it matter? (I prefer self server to store my data.
Usually, cloud servers run on Linux. You can choose any OS according to your options.
What about personal server (raspberry pi 4). Then how do I access from cell phone? (That way I do not think I need gsm from Google. Right?

Can you make the device call you back and listen to the microphone on the device ?
It's a very interesting idea. In order for that to be possible, a continuous phone connection must be established, but that part may not be easy.
What phone did you select in order to order the sim card? It seems a phone needs to be selected - no option to enter simcom as what the sim card is for.
Since I chose a data-only SIM card, I did not choose which phone to use.
