No location with ESP32 and SIM800L

Open albertomercurio opened this issue 4 years ago • 15 comments

What type of issues is this?

[ ] Request to support a new module [ ] Bug or problem compiling the library [ x] Bug or issue with library functionality (ie, sending data over TCP/IP)

What are you working with?

Main processor board: ESP32 Modem: SIM800L TinyGSM version: 0.10.1 Code: AllFunctions

Scenario, steps to reproduce

I'm using the TTGO T-CALL board, with ESP32 and SIM800L integrated. The function modem.getGsmLocation() give always false if i set the TINY_GSM_TEST_SSL as true. But if if set SSL to false my location is fixed correctly. Why this happen? I'm Using the Things Mobile simcard.

No clue. I don't have a SIM800 model that supports SSL. Post the AT log.

SRGDamia1 avatar Apr 06 '20 21:04 SRGDamia1

How can i do that? However i noticed that sometimes also with ssl setted to false it doesn't take the location. Is it normal? My signal quality is 24.

Look at any of the examples and use the dump AT code.

It looks like you did get the location, just not on the first try. I think that's normal; it takes a while to "settle" on a location which is why that program tries several times with a wait between.

I'm not sure what went wrong with you TCP connection in there, though. It looks like it closed before getting the response. Has that been happening with other sites?

SRGDamia1 avatar Apr 08 '20 12:04 SRGDamia1

I precise that TCP connection works. SSL doesn't work, also with another server:

Hm. It's like it's closing the connection as soon as it is open. Unfortunately, I just don't have a SIM800 variant with SSL support myself to test so the best I can do is ask you to make changes and keep posting the AT log for me.

First thing it to try removing the "stop" from the secure connect function. Open TinyGsmClientSIM800.h and comment out line 135 stop(); in the GsmClientSecureSim800 connect function. (Make sure you're in the client secure section!) The intent of that particular stop() is to always make sure the socket is closed and thus available to make a connection before attempting the connection. But I've seen it happen with u-blox modules that if you call stop() when there wasn't actually an open connection it waits until you've made a connection later and then "helpfully" immediately stops that connection. It looks like your SIM800 might be doing something similar.

Are you ok with the location issue?

Do i remove the comment on stop();? This time location didn't work. Sometimes it work, but sometimes not.

Boo, removing that stop doesn't seem to have made the slightest difference. You might as well put it back.

For location, I think the module just needs to be connected to the network for a fairly long time before the location works. I honestly haven't had much success with it. 2G is dieing in the US and where I am I didn't have many places where I could get much signal to test with even before we were all restricted to stay-at-home.

I don't have a next suggestion; I'll have to think on it and google around. Are you absolutely sure your module has the right firmware for SSL? On mine I get "ERROR" back for any SSL commands I attempt, so I'd guess the fact anything happens for you might indicate it works. but I know most people's success with SSL on the SIM800 is very firmware dependent.

I should have the latest version 14.18. What sim module do you recommend?

albertomercurio avatar Apr 08 '20 22:04 albertomercurio

I'm sorry, I don't have any recommendations ready. I would suggest you google around for other people's results with that particular firmware. The library is using the documented commands to use SSL on the TCP connection; I really have no idea why it's not working.

Ciao @albertomercurio , did you eventually find a solution?

gorghino avatar May 21 '21 14:05 gorghino

Hey, @gorghino and @albertomercurio did you guys find any solution?

I'm having the same issues, but for me it is not even working without SSL. I have completed all the troubleshooting steps, made sure i have stable power and proper communication the module. The allFunctions example is working correctly for everything except GSM location and balance check, but i doubt the issues are related.

I have the exact same module but firmware is 11.3.

Attached is AT logs. allfunctions_GSM_location.txt

@SRGDamia1 could you maybe weigh in on this?

could you solve this problem. I'm facing with same problem. Need help

I never got this board to function as I desired. If I recall correctly, there are issues with the board design which should be documented in the issues section of this repo. I bought the Arduino MKR GSM 1400 instead and that was way more reliable.
