If you want to use API why not use Telegram instead? It's free and easy to configure. See this: https://forum.logicmachine.net/showthrea...1#pid17111

Hello,
with the instruction and files in post 3 I am now able to receive and send sms. THX! I also managed to reboot via SMS and get back some information (e.g. IP) when sending a sms with "status" as content to LM. I now want to get back the signal status of the modem via sms. ASFAIK the AT-Command "AT+CSQ" delivers this information but unfortunately I have no clue how to implement this (my lua and AT-Command skills are not the best ![]() Can anyone help? Thx in advance!

1. Modify the user library send function so it returns the command reply/result:
Code: 12345678910111213 -- send command to terminal
function AT:send(cmd)
local res, err = self.port:write(cmd .. '\r\n')
local reply
-- write ok, get local echo
if res then
res, err = self:readuntil(cmd)
reply = self:read()
end
return res, err, reply
end2. Add before handler = function(sms) in the resident script: Code: 123456789101112131415161718192021222324 readcsq = function()
local res, err, reply = modem:send('AT+CSQ')
local rssi
if reply then
rssi = reply:match('%+CSQ:%s+(%d+),(%d+)')
end
rssi = tonumber(rssi) or 0
if 2 <= rssi and rssi <= 9 then
quality = 'marginal'
elseif 10 <= rssi and rssi <= 14 then
quality = 'ok'
elseif 15 <= rssi and rssi <= 19 then
quality = 'good'
elseif 20 <= rssi and rssi <= 30 then
quality = 'excellent'
else
quality = 'unknown'
end
end
csqtime = os.time()3. Add before udphandler(server) in the resident script: Code: 1234567 now = os.time()
delta = math.abs(now - csqtime)
if delta >= 15 then
csqtime = now
readcsq()
endThis will read the signal quality every 15 seconds and will set global variable quality that you can use in the SMS reply message.

Is it possible to change APN via SMS and reconnect to the new APN? I am sure it is but my skills ...
I need this to connect to my LM in case the VPN is down. Normally I use the APN "internet.telekom, tm ,tm" and do not want to change this default setting (bacause of security reasons) - with this APN you get a private WAN-IP like 10.x.x.x and AFAIK you can not connect to private IPs. With the APN "internet.t-d1.de, internet, t-d1" you get a non private IP like 32.x.x.x and you can connect to it. Another point: In the resident script the PIN code needs to be set - either as a number or a object-variable. Is it also possible to get the PIN code out of the system preferences where it usually also has to be set? THX in advance! |
