Hi, I have the same issue but with just one header: ``` char* header = "auth_token:11111111-2222-3333-4444-555555555555" uint16_t rc = sim800l->doPost( SIM_SERVER_URL, header, "application/json", "data", 10000, 10000 ); ``` ``` 13:46:58.916...

I figured out that it is connected to the length of the char array - an array with more than 34 characters results in getting stuck. With

Sim800 Object initialization is similar to the examples: ```sim800l = new SIM800L((Stream *)sim800l_serial, SIM_RST, 200, 512, (Stream*)&Serial);``` Debug message for this part: ``` SIM800L : Send "AT+HTTPPARA="USERDATA","authtoken:1234567890abcdefghijklmnopqrstuvwxyz"" SIM800L : Receive...

Ok after some research I finally figured out a solution. As described [here](https://arduino.stackexchange.com/questions/37221/common-ground-serial-communication-trouble-sim800l) the SIM800L module seems to have issues with automatic baud detection. Setting the baud rate manually solves...

Add ``` import os gpu_id = "3" # the GPU id you want to use - also multiple GPUs possible (separated by comma) os.environ["CUDA_DEVICE_ORDER"] = "PCI_BUS_ID" os.environ["CUDA_VISIBLE_DEVICES"] = gpu_id ```...
