Hi,

I have purchased an official SIM7600 PCIE from simcom, and would like to use this on the T-SIMCAM as the sim module provided is outdated and lacks some AT commands. However, when I try using the official SIM7600 PCIE, the T-SIMCAM keeps disconnecting and reconnecting when plugged in.

Does anyone have any ideas?

Cheers

@saiteja-vellanki how did you fix it?

@teastain2 I seem to have a similar problem here. Mine seems to keep reconnecting and disconnecting though.

I have had my T-SIMCAM for a few months and never ran into issues until last week. I have been unable to flash or connect to the device.

I have tried the following:

1. press Boot and hold it
2. press reset and then release
3. release Boot

I am then able to connect, but as soon as I try doing any form of operation, such as clearing flash, I get an error. I am only able to connect via ESPTOOL.JS and when i try connecting with platform.io i get the error telling me it doesn't exist

Edit:
It seems like every 3-4 seconds the device keeps disconnecting and reconnecting

Hello,
