https://devzone.nordicsemi.com/f/nordic-q-a/87034/nrf9160-rev2Hello Dear, Why the time of uplink state is 950 ms if the data packet size is 0 Byte? Can we say that every time a data is sent, it takes 950 ms to get the transmission protocol?en-USTelligent Community 13Wed, 20 Apr 2022 07:21:48 GMThttps://devzone.nordicsemi.com/thread/363764?ContentTypeID=1Wed, 20 Apr 2022 07:21:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b323c1d0-6436-40a9-8528-eeb86e90e45fH&#229;kon Alseth<p>Thanks for clarifying. Yes, I see the same.</p> <p>This sounds a bit strange, even if NB1 is significantly slower than LTE-M, it should be quicker than this. I&#39;ll let the maintainer of the power calculator know about this, and we&#39;ll have a look.</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/363698?ContentTypeID=1Tue, 19 Apr 2022 17:28:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e55e4593-9794-4d74-aae8-734771457f7dMohamad Kheireddine<p>My question is in the mode NB-IoT not on LTE-M</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/363628?ContentTypeID=1Tue, 19 Apr 2022 13:40:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bbef648a-17e3-4442-bc3e-2278ddadca63H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>That is strange, a 0 byte userdata payload should be alot faster to transfer than almost one second. Here&#39;s the timing that I got when I tried the same:</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1650375546159v1.png" alt=" " /></p> <p>Maybe it did not refresh the former selection of bytes? Could you try refreshing the page and inputting 0 bytes upload again?</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
