Now it is doing this
20:57:08.013 -> ---> AT+GSN 20:57:08.013 -> <--- 869[IMEI number] 20:57:08.047 -> Module IMEI: 869[IMEI number] 20:57:08.081 -> ⸮gO#⸮⸮߮Yᱷ⸮⸮⸮ SIM7000 MQTT Example
I notice the gibberish output after IMEI. Baud rate issue?
em... I really didn't do anything now my Arduino can't communicate with the SIM7000. No response from AT command. USB direct connection to my computer still works. Did some components fail on the board?
Does the battery have the correct polarity? Red wire should be on the left side of the connector when you plug it into the board.
Yes, I have confirmed battery connection is correct
Please check the physical connection on pins 10-11 on the shield. If the green "PWR" LED on the board is staying on but you're not able to communicate with it, this may indicate an issue with the hardware connection being flaky.
I loaded MQTT example to my Arduino UNO and SIM7000C, it keeps resetting. I do have battery attached and LTE_demo runs ok.

It just keeps repeating above.
