      Hi,

      the first version of documentation for SIMCom SIM7022 how to

      attach the device to Telekom NB-IoT network of IoT Creators and get assigned an IP address. Send “Hello World” uplink message via UDP from device to IoT Creators UDP server. Send “Hello Device” downlink message via UDP from IoT Creators portal to device. Receive “Hello Device” downlink message on device via UDP from IoT Creators UDP server.

      is available now in IoT Creators documentation library.

      https://docs.iotcreators.com/docs/simcom-sim7022

      Would be great if you check it and give me some feedback for improvements and corrections.

      Regards, Roland

      @MeneerJacco you might check this entry as well, which points to a small web page doing the calculation work reg. at+cpsms command.
      https://forum.iotcreators.com/topic/642/psm-calculation-tool-t3412-t3324-value-decoding?_=1622307153602

      Be aware, that entering the value via at+cpsms is only a request towards the network. The network decides if your values are committed. To check the network reply, use

      at+cereg=4

      and check the values via:

      at+cereg?

      You can paste the reply in the above mentioned web page as well to get the values ‘decoded’.
      My recommendation: set the active time (T3324) to a minimum and use the ‘RAI’ - release assistance indicator after sending data to shorten the RRC connected mode to a minimum. Then your device will enter PSM faster.
      BR,

      @Roalnd-Baldin Has this been rolled out already? Do you have any idea when we can expect it? Thanks in advance!

      @IoT-Arista Hi, thanks for letting us know! We moved our documentation library to docs.iotcreators.com - but I think you figured that out. I will try to figure out if we can change or remove the broken links from google search. Thank you!

      Hi Eben,

      Quick feedback: I can use GNSS and TCP at the same time using the SIM7000E using the latest firmware, which I had to update beforehand.

      Best Regards,
      Daniel

      I have been looking to this post:

      https://forum.iot.t-mobile.nl/topic/310/sim7000e-accepteert-de-genoemde-commandos-niet?_=1591271570193

      I like to have it work with T-mobile NB IoT on a combination of the SparkFun SAMD21 Mini Breakout connection and the SIM7000E break out board.

      Is there anybody who has succeeded to do so with Arduino code?

      Thanks in advance for your answer.
