Show this? Can you give me a full screenshot? I've never seen this error before, and I don't know which software this is from

[toneshoo]

i tried to change the baudrate but samething also the 2 led are not blinking

[lewisxhe]

Monitor baud rate is 9600, change sketch baud rate to 9600 or set monitor to 115200

[toneshoo]

alright one problem out of the way but still the gps and gsm led are not on and i get this

You need SIM-HAT hardware support to run. The examples above all need SIM-HAT hardware support. Please run the minimum ATDebug to test and read the README first.

[toneshoo]

this is kind of my first time here could you explain more ?

[lewisxhe]

All examples with SIMhat in their names require the support of this hardware to run https://www.lilygo.cc/products/lilygo%C2%AE-t-simhat-can-rs485-relay-5v

README explains which examples can be used and which cannot

[toneshoo]

i saw many videos on youtube that connected a wifi and gps to the same excat model i use which is a7670e esp32 wroover e if i cant use these libaraies how should i proced?

[lewisxhe]

What do you mean? I don't understand what you mean?

[toneshoo]

before i decided to buy this model which is A7670E
i checked some youtube videos to make sure it can work without any extra hardware but if the examples above require some extra hardware can you help me find examples for the board itself alone ?

[lewisxhe]

[toneshoo]

hmmmmmm wait so in order to be able to use gsm and gps i need to buy the extra hardware ??

[lewisxhe]

Well, to use GSM and GPS you only need to buy A7670. SIM-HAT is a separate additional hardware, you can exclude it completely, I just want to tell you that SIMHAT*** example requires additional hardware support, understand? I think I made it clear.

[toneshoo]

yeah i get it now what tuturial do i follow to start the gps and gsm right now there leds are off

[lewisxhe]

ATDebug

[toneshoo]

done that already every time i check the serial moniter when uploading any code i always get Failed to find INA219 1 chip in
