In this Sensor Hub - 4G Data Logger is possible to debug modem quectel with at command from debut uart connector?

Thank you!!

Hey there,
Thank you very much for choosing SenseCAP. This is Violet from Seeed. Apologies for the inconvenience. This might be because the roaming function is not activated yet. We will upgrade the firmware via OTA in the near future. At the current stage, could you please download the new firmware from this Github link. And please let us know if the problem remains.

And here is SenseCAP Sensor Hub User Guide. Hope it’d come in handy when you use the product.

@violet another information, how can i configure the sending of data from the gateway every 60 minutes?

Hi Gabriele, for SenseCAP Sensor Hub, the default data upload interval is every 60 minutes. And if you would like to configure it to different intervals, please kindly refer to this user guide. It should be in Chapter 4.4.1.

Let us know if you need any further support. Thank you!
