Reactor LTE problem - BMSimon - 27.05.2024
Hi guys
I received my LogicMachine5 Reactor LTE last Friday and I'm trying to get the LTE connection up and running before sending it out to our customer.
I followed the instruction you posted to another customer with a similar problem, and got these results:
Code:
* arg: 1
* string: open port
* arg: 2
* string: /dev/ttyUSB2
* string: AT&F
OK
+CPIN: SIM PIN
ATE1
OK
AT+CGDCONT=1,"IP","internet"
ERROR
ATD*99***1#
ERRORAnd ran the other script to check signal strength i assume?
Code:
* string: Signal: 29
* string: SIM: unknown
* string: Network: no infoAm I missing something?

Remove PIN code protection from the SIM card and try again.

Thank you, that worked
1 more question!
How do I configure ZeroTier without setting a Gateway IP?
RE: Reactor LTE problem - admin - 27.05.2024
ZeroTier needs internet access so it won't work without a gateway/DNS. When 3G/4G connection becomes active it will override the default gateway so all external traffic is routed via the mobile network.

Does that mean that I can't use ZeroTier?
I waited until I could see my 4G IP under 3G/4G settings, then I clicked on ZeroTier and it came with a red message that I need a Gateway IP before I can use ZeroTier!
RE: Reactor LTE problem - admin - 27.05.2024
It will work, but you need to set gateway and DNS in Ethernet settings. Otherwise you will get this error message.

Perfect, can I set my sim cards IP as gateway? and just use google as DNS?
RE: Reactor LTE problem - admin - 27.05.2024
Set proper gateway for the local network. You can use Google DNS.
When the mobile network is connected the default gateway will switch to the mobile network automatically.

You need to set gateway in Interface eth0 configuration. This won't affect 3G/4G connectivity.

Good evening,
i come back on this post, anyone can share with me the script to have the LTE signal power?

Hi Cristian,
not remember all details now, but I added to my modem script's this part (in incoming sms handler):
Code:
-- incoming sms handler
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
grp.write('0/0/40', quality) -- Modem signal level write to group
endFor modem I use resident script, working every 10 seconds.
Hope it helps.
If not - I will look deep and will write my modem's script and info. I have 2G BGS2T modem, connected to usb on LM through USB2RS232 adapter. Working already ~8 years without problems.
BR,
Alex
