AllFunctions example not working, getting brownout triggers #21

Closed ticketos-pl closed 4 years ago

ticketos-pl commented 4 years ago

Just got my t-sim7000g board, wanted to give it a simple test, but I'm failing on running the AllFunctions example from this repo.

Strange thing - I got modem info returning data only once.

Console output:

.... and so on

I have the same situation when using http client example from tinyGsm repo: https://github.com/vshymanskyy/TinyGSM/blob/master/examples/HttpClient/HttpClient.ino

Console output:

Any ideas? I also have t-sim800l board, and I didn't have such issues.

Just to make sure as you are referring to SIM800 - are you using NB-IoT SIM card or common LTE/4G?

Sorry it turned out to be a low quality USB-C adapter I was using with my mac. That's why I had brownout triggered.

Changed to a different adapter and now the example code is running without any issues :)
