Hi Thorsten,
thanks a lot for your reply. I will test the things you suggested but it might be a few days until I reply here with the results.

Regards,
Lorenz

@Ronan-Lacroix
Hello Ronan,
thanks for your answer and suggestion.

To prevent the interference between PSM and eDRX, I did another test where I turned off PSM and enabled eDRX. And then it worked. I got the +CEDRXRDP:5,"0010","0010","0000"

Those are the two tests I did

python3 packet-sending.py --interval 60 --finish-after 3 --release-assistance 1 --psm-enabled 0 --edrx-enabled 1
python3 packet-sending.py --interval 60 --finish-after 3 --release-assistance 1 --psm-enabled 0 --edrx-enabled 0

And here are the results with edrx enabled and with edrx disabled:

On the charts you can see that the average power consumption went down from 0.8mA to 0.3mA with eDRX enabled which is good.

I will probably write a blog post about receiving messages during eDRX (I can share it here if you want). I read that the network operator can buffer a MT (mobile terminated) message of up to 100 bytes (can’t quite remember the exact number). Can you confirm that?

Regards,
Lorenz

@Aleksandra-Klinkner
Thanks for your input.

As @Stefan-de-Lange pointed out, I am setting the PSM Tau update to 10 hours and the network acknowledges it +CEREG:5,CB52,02992008,9,,,00000101,01000001

How should I proceed now?
There is a Quectel Webinar which I will attend tomorrow where I will ask that question, but in case I don’t get an answer, is there a way to open a dedicated support ticket?

I have a bc68 (same chipset as the bc95g) where I will try it this week, but I expect the results to be the same…

Just to point it out again. If this behaviour cannot be changed, it makes it very very hard to develop battery powered applications if the device registers to the network every hour…

@Stefan-de-Lange
Thanks for the quick answer. It is:

Unfortunately I could not add .txt files to the forum here as it is not supported. So here is the entire at command log:

quick amendment: I am connecting from Germany, so even though the network is registered with roaming, I am in the home network of 1nce.

Also, is it possible to edit previous posts? (I did not find an option for it).

Dear iotcreators,
first of all, I really appreciate this forum. Thanks for setting it up.

I have observed a behaviour with the nb-iot modem bc95-g that I cannot explain. (using 1nce sim cards).
Event though the psm is set to 10 hours, and I am sending a packet every 1.5hours, the modem registers to the network every hour.
I asked that question to tekmodul, and they said that it might be related to the automatic network registration (i.e. at+cops=0. But I did another test with at+cops=1 (see image below) and I am still getting the connection every hour. What is the reason for that?
Could it be maybe because I am registered with roaming? +cereg: 5. (I have not found a way to select the home network though, i.e. +cereg=1)

The picture shows the output of a test run where 16 bytes are sent every 1.5 hours and it stops after 6 iterations. The crosses on the chart indicate when the packets where sent.

Here are some AT logs:

@Ronan-Lacroix
Hi, thanks for the quick answer. The AT+QNWINFO command is not available on my module. But I used at+cops? below and it gives the 26201 network.

So I am registered to the correct network (with automatic selection) but I don’t get the correct +CEDRXRDP: 5,“0010”,“0010”,“0100”. Any other clues? Does the bc95-g module from quectel not support it?

# connected to 26201 operator
at+cops?
+COPS:0,2,"26201"
OK
at+cereg?
+CEREG:5,5,CB52,02992008,9,,,00000101,01000001

# turning off edrx
AT+CEDRXS=0,5
OK
+CSCON:1
+CSCON:0

# turning it back on with urc enabled
AT+CEDRXS=2,5,"0010"
OK
+CSCON:1
+CSCON:0

# not getting a urc, so manually checking the status
AT+CEDRXRDP
+CEDRXRDP:0
AT+CEDRXS?
+CEDRXS:5,"0010"
# waiting for two minutes
AT+CEDRXRDP
+CEDRXRDP:0

Kind Regards,
Lorenz

Hello,
I am using the Quectel BC95-G and a 1nce sim card.
Can you confirm that edrx works also for the 1nce network (which uses the Telekom network?)

Or am I doing something wrong with the AT commands?

# software revision
ati
Quectel
BC95-G
Revision:BC95GJBR01A04

# pinging google dns server. Network is there.
at+nping=8.8.8.8
+NPING:8.8.8.8,110,1840

# 20 second eDRX Value
AT+CEDRXS=1,5,"0010"
OK
AT+CEDRXS?
+CEDRXS:5,"0010"

OK
# checking edrx status. 0 means not working
AT+CEDRXRDP
+CEDRXRDP:0

Using our nb-iot power consumption tool and enabling edrx with the above, I cannot see any paging spikes (which I would expect every 20 seconds). The chart shows 3 UPD packets being sent to the server and the green cross shows the time when it arrived on the server.

Would be happy about some help here, thanks.
