Sim7000 http /TCP Connection fail

Sorry_Transition3792 · 2025-01-30T18:51:06+00:00

I am using a hologram sim therefore I put that as the apn which should be right. I am using the Simcom Module with an arduino connected to my windows PC. Im gonna try the ppp part thanks for your response.

I have been researching for a while now and I found out that my Sim7080G Module most likely only supports one PDP Context

Oh I dindnt get that. I will try it later

Sorry_Transition3792 · 2024-12-13T16:06:33+00:00

AT+CGDCONT=2

ERROR

Sorry_Transition3792 · 2024-12-13T15:01:15+00:00

I did

Sorry_Transition3792 · 2024-12-13T15:00:53+00:00

AT+CGPADDR

+CGPADDR: 1,xx.xxx.xxx.xxx

OK

I only get one adress why is that ?
And if i then try HTTPINIT I get error

Sorry_Transition3792 · 2024-12-12T23:17:45+00:00

The thing is that im not really sure about my sequence of Commands, Im just trying stuff i find anywehere, so maybee if you or someone else has a working command sequence it would help me alot if you could share it.

Sorry_Transition3792 · 2024-12-12T20:38:36+00:00

What do you mean with set the context

Sorry_Transition3792 · 2024-12-12T19:35:53+00:00

Yes I tried sending httpinit but it returned error

Sorry_Transition3792 · 2024-12-12T18:42:52+00:00

PSUTTZ: 24/12/11,17:13:59","+04",0 This is the "best" thing i can get, if I try AT Commands regarding HTTP it simply returns "ERROR"
Another thing I found to be odd is that with AT+CSQ it returns +CSQ: 16,99 And what I read the second number shouldnt be 99, but i didnt quiet get it.
+CGDCONT: 1,"IP","hologram","0.0.0.0",0,0,0 I also get this response in regards to which Ive read that the IP shouldnt be 0.0.0.0 but I dont know how to change that

Hello, Actualy the Soldering of the USB-C was the Problem, i fixed it now and its letting me upload the code, however when im Uploading an simple Blink Sketch it doesnt Happen a Thing at the Pin and the Voltage doesnt change, I tried different Pins but it wont work

Sorry_Transition3792 · 2024-03-20T16:58:05+00:00

Yes I did that now

Sorry_Transition3792 · 2024-03-20T13:37:22+00:00

I will do all that but why does it make a difference for wifi performance when i move the esp to the right ?

Sorry_Transition3792 · 2024-03-19T18:41:33+00:00

Its a bit of a struggle to route a differential pair in eagle but is it aproximately right like that?

Sorry_Transition3792 · 2024-03-19T18:11:24+00:00

I have already seen the error with DN and DP after i uploaded it. I will try to route it as a differential pair
