    • Sim error after configuring COPS/PLMN with Quectel BG96

      Hey all,
      I am trying to connect a Quectel BG96. Every time after configuring

      AT+COPS=1,2,"20416",9

      It says

      CME Error: 13

      Also a simple command to retrieve the IMSI AT+CIMI gives an error then.

      When I reset the modem and use AT+CIMI again, it works and returns the IMSI. However, after trying to configure the COPS again, the error comes back…

      Any ideas?

      Should be fixed now!

      @Muhammad-Tahir-Abbas

      Sorry for the inconvenience. I think you’re trying to use a license which was expired months ago.

      I’m double checking it with my colleague and will get back to you tomorrow again.

      @mybeepad-0

      One day you will have dreams about AT-commands

      (I am talking from experience) 😅

      @mybeepad-0

      when using APN cdp.iot.t-mobile.nl you can indeed only access our servers via 172.27.131.100. We have different servers available: MQTT, UDP, CoAP, LWM2M and NON-IP.
      By using on of our services you will be able to get your device data in your preferred platform via webhook (http/callback).

      when using APN m2m.public.nl you can send data to any IP destination on the public internet.

    • RE: NB-IoT coverage Hungary, Budapest

      Hey Tibor,

      Shoudn’t you also execute AT commands to configure the band and the PLMN id?

    • RE: Can I send my downlink directly via UDP?

      By using eDRX the device is able to receive downlink messages without sending uplinks.

      Let me know if this helps:

    • RE: Is NB-IoT vertically polarised?

      Copy / paste what one of my colleagues wrote:

      I must admit I am not sure regarding the polarization used on our cell sites, xn--an article stating that most operators use +/- 45-88b is probably correct. I’ll try to find out and let you know.

      That said, knowing the base station antenna’s polarization is not as important as it might appear at first glance. In fact, it only matters in cases where a direct, uninterrupted, line-of-sight exists between the base station antenna and the UE antenna. In most practical cases, the signal the UE sees (and what the base station sees in the uplink case) is a mixture of signals that have been reflected off of and scattered by all kinds of objects (mountains, buildings, trees, vehicles etc.) in and around the line-of-sight. This is called “multipath”.

      In a multipath environment, there is no way to predict the polarization of the signal at the receiving antenna, even if the polarization of the transmitting antenna is well known.

      This is why the more complex variants of LTE (CAT.1 and above) require at least two antennas, which are typically set up to be sensitive to signals with different polarization.

    • Is NB-IoT vertically polarised?

      I have no clue what this means.

      😂

      But I got this question from a customer and I thought it makes sense to try to get the answer here.
