How can I read the incoming SMS from the AutoPi’s Sim?
In the terminal, nothing happens with “ec2x.list_sms” or the local terminal with “autopi ec2x.list_sms” command.
It would be very interesting to be able to read them from the dashboard …
Thanks!

It would have been nice to be able to send SMS too, then you could check the amount of data on prepaid cards.

Hi @atlantisworld and @el93mon
Great ideas. At the moment we dont have a graphical interface for reading and sending SMS, but its actually already possible.
From the terminal you should be able to query any command to the modem. This is done with:
ec2x.query
This is actually what the ec2x.list_sms does, if you look in the code:
ec2x.query 'AT+CMGL="all"'
The command should return a list of messages, each with a specific index. To read the index you want you can use this command:
ec2x.query 'AT+CMGR=<index>"'
Replace <index> with a number.
So basically any command supported by the modem, can be send directly from the terminal.
Your device need to be online to do so.

I also see ec2x.list_sms not returning any sms’s sent -
$ ec2x.list_sms
'ERROR: {''reason'': None, ''type'': None}'
$ ec2x.query 'AT+CMGL="all"'
'ERROR: {''reason'': None, ''type'': None}'
I’m testing this by sending an sms from my phone with delivery report enabled. If the autopi is off, I don’t get the delivery report but with it on the delivery report is delivered pretty quickly … so looks like the message is getting to the autopi.
If I put the sim into a spare phone I don’t see the old messages but new messages come through.
I’m wondering if the autopi is reading / deleting all messages ?
Hi Peter
Can you try to run the following command?
ec2x.sms_format_config value=1
Afterwards, you should be able to retrieve the text messages from the modem.
We have a startup task that executes the above command that enables us to retrieve the messages, but the value is not remembered when the modem is powered off, so it needs to be executed each time it starts.
But… It is currently disabled because it fails if there is no sim card present, a fix is on our roadmap, but in the meantime, you can run the command manually, or maybe set up a job that does it on startup.
How exactly the text messages work, like where they are stored, I’m not entirely sure, but I think it’s on the modem, so that’s probably why you don’t see the previous messages when you move the SIM card to a spare phone.
Best regards

That command also gives me an error -
peter26@Kona $ ec2x.sms_format_config value=1
'ERROR: {''reason'': None, ''type'': None}'
I’ll see what I can dig out.
It looks like I’ve got some bigger issues with 4G. Logs include -

Apr 15 17:57:53 raspberrypi qmi-manager[3578]: [ERROR] No SIM card present
I’ve verified the SIM is insert the right way and it clicks, contacts are clean and I’ve also tried a piece of paper to put the SIM on the contacts.
This used to work ( in early testing ).
I did noticed that qmi-manager was updated on 1st March -
root@autopi-41ab498c8cb8:/var/log# ls -l /usr/bin/qmi-manager
-rwxr-xr-x 1 root root 13130 Mar 1 21:17 /usr/bin/qmi-manager
I’m not sure if this is right or not.
Anything else I can try to diagnose the situation ?
Thanks.
Yea !
I took the autopi appart, re-seated and cleaned and now looking much better

How do i delete SMS, i now have 255 and its probably why the AutoPi stopped responding/wake up anymore?
/Mats
Guessing, to delete all -
ec2x.query 'AT+CMGD=1,4'

Here is my custom code to read SMS’s on autopi, forward to telegram and delete once forwarded. My main reason for doing this is to get any “out of credit” messages from the operator.
import logging
import requests
import os
import re
log = logging.getLogger(__name__)
# Telegram tokens - see https://www.mariansauter.de/2018/01/send-telegram-notifications-to-your-mobile-from-python-opensesame/
#
bot_token = 'xxx'
bot_chatID = 'xxx'
def forward():
"""
Poll for sms and forward to telegram
Once sent, delete from autopi
"""
__salt__['ec2x.query']('AT+CMGF=1')
args = ['AT+CMGL="ALL"']
res = __salt__['ec2x.query']('AT+CMGL="ALL"')
if 'data' in res:
allmessages = parse(res['data'])
for message in allmessages:
log.info ("SMS: "+message['message'])
bot_sendtext('SMS From: '+message['from']+'\nDate: '+message['date']+'\n\n'+message['message'])
__salt__['ec2x.query']('AT+CMGD='+message['index'])
return {"msg": "Forward finished"}
# parse output to an array of dictionary
#
def parse(x):
res = []
i = 0
while i < len(x):
m = re.match('\+CMGL: (\d+),\"(.+)\",\"(.+)\",(.*),\"(.+)\"', x[i])
if m:
res.append({'index':m.group(1),'from':m.group(3),'date':m.group(5),'message':x[i+1]})
else:
log.info ("SMS: No match "+x[i])
i += 2
return res
# send message to telegram
#
def bot_sendtext(bot_message):
send_text = 'https://api.telegram.org/bot' + bot_token + '/sendMessage?chat_id=' + bot_chatID + '&parse_mode=Markdown&text=' + bot_message
requests.get(send_text)

Had to do the same to mine on second day of ownership.
That retaining system and socket don’t provide a high enough contact force, it would seem.
Wonder if it will cause issues long-term due to vibration…
Hi, I am also using your custom code since 2019! for some reason unknown to me it stopped working …
