Hello,

i’m trying to configure a listening port. in Ublox Sara N310. the device receives data only on send. how to make the device to collect data automatically?

hi @trick2011 , i see that you have edrx enabled (or it seems so, i am not completely familiar with your modem). in this case, to send data to the device you can use our edrx api explained here https://docs.iotcreators.com/reference/send-base64-edrx-downlink-message , so that you don’t need to send data in order to receive.

Hope this helps!

@MarcoPeli I get the “msg”: “Accepted”, “code”: 1002 from the web api. but nothing on the device. any suggestion?

ji @trick2011 , that means that our api is properly working. please verify on your device that edrx is enabled. Also, edrx is not supported everywhere, where is the device located?

hi @trick2011, edrx is supported in the netherlands, i know that under roaming with vodafone libertel it works perfectly

@trick2011 , to help you troubleshoot your problem, you can also refer to our docs here that explains eDRX: https://docs.iotcreators.com/docs/nb-iot-network-information, and also here on the official gsma website you can find infos about the edrx parameters in europe https://www.gsma.com/iot/mobile-iot/roaming/ . Also, to be able to send data to your device through eDRX, you will need to send at least one payload from the device to our platform, because the mobile network needs to know the ip address of your device in order to correctly forward the message through eDRX.
Hope this helps!
