[x ] I have read the Troubleshooting section of the ReadMe

What type of issues is this?

[ ] Request to support a new module

[ ] Bug or problem compiling the library [ ] Bug or issue with library functionality (ie, sending data over TCP/IP) [x ] Question or request for help

What are you working with?

Modem: DFRobot SIM7000E Main processor board: ESP32 Devkit 4 TinyGSM version: (0.11.5) Code:

/**************************************************************
 *
 * For this example, you need to install PubSubClient library:
 *   https://github.com/knolleary/pubsubclient
 *   or from http://librarymanager/all#PubSubClient
 *
 * TinyGSM Getting Started guide:
 *   https://tiny.cc/tinygsm-readme
 *
 * For more MQTT examples, see PubSubClient library
 *
 **************************************************************
 * This example connects to HiveMQ's showcase broker.
 *
 * You can quickly test sending and receiving messages from the HiveMQ webclient
 * available at http://www.hivemq.com/demos/websocket-client/.
 *
 * Subscribe to the topic GsmClientTest/ledStatus
 * Publish "toggle" to the topic GsmClientTest/led and the LED on your board
 * should toggle and you should see a new message published to
 * GsmClientTest/ledStatus with the newest LED status.

Scenario, steps to reproduce

Connecting the board to an external power supply, giving it 9V. Giving it a common ground connection. Connecting RX and TX on, D00 and D001 on shield to Pin 16 and 17.

Expected result

Any kind of connection to happen, at least read the modem name.

Actual result

No connection seemingly happen at all, it tries all baud rates and tries to do it's code but without being successful. I havre a feeling it's either wiring issue, and I'm posting this in the wrong place or the code.
