Examples stopped working after update to 2.1.0

[razvandragomirescu]

The new examples compile fine but fail to start the modem. The output on the serial monitor is

Enabling the supercapacitor charger...
Supercapacitors charged!
Enabling 9603N power...
Starting modem...

It appears to freeze there. I got no errors when compiling or uploading. Any way to debug this?

[razvandragomirescu]

The old examples still work fine (on the same hardware) with version 1.2.3, so it's not a hardware issue.

Hi @razvandragomirescu ,
Do you see the same behavior on all of the Iridium examples? Do the simple examples like Example7 work?
Best wishes,
Paul

[PaulZC]

Also, please make sure you have "RedBoard Artemis ATP" selected as the board type. ("Artemis Module" will not work.)

[PaulZC]

To enable debug messages for the Iridium serial communication, change the false in this line to true:

Artemis_Global_Tracker/Software/examples/Example7_GetIMEI/Example7_GetIMEI.ino

Line 63 in 8094e14

#define DIAGNOSTICS false // Change this to true to see IridiumSBD diagnostics

Hi @razvandragomirescu ,

If you have time, please do try uploading one of the new binaries onto your board. Details are here. That way we can rule out the way the code is being compiled.

If you run the Example7 binary, you should see:

Artemis Global Tracker
Example: Get IMEI

Please check that the Serial Monitor is set to 115200 Baud
and that the line ending is set to Newline.
Then click Send to start the example.

Enabling the supercapacitor charger...
Supercapacitors charged!
Enabling 9603N power...
Starting modem...
IMEI is 3004-------4090.
Putting the 9603N to sleep.
Disabling 9603N power...
Disabling the supercapacitor charger...
Done!

Running Example7 with DIAGNOSTICS set to true should produce:

Artemis Global Tracker
Example: Get IMEI

Please check that the Serial Monitor is set to 115200 Baud
and that the line ending is set to Newline.
Then click Send to start the example.

Please also check that the red 9603N POWER LED turns on when you see the "Enabling 9603N power" appear.

If you want to debug further, you can try probing on the TX1 test point on the rear of the PCB. You should see the serial AT commands being sent to the modem at 19200 Baud (3.3V). The replies - if any - will appear on RX1.

Best wishes,
Paul

I have tried both on a new computer (Windows this time to rule out an issue with my Mac) and with the binaries (uploaded from Windows using the binary uploader). Same result, it freezes at "Starting modem...". The orange "charging" LED lights up briefly while the console says "Waiting for supercapacitors to charge", then the RED "9603N Power" LED lights up but the modem doesn't appear to respond.

Once again, this works fine with the older 1.2.3 firmware.

Hi @razvandragomirescu ,

Thank you for investigating this.
Just to be clear, have you tried the Example7 binary? And does that freeze at the same place?
(I'm trying to rule out an issue with re-starting Serial1 after the Artemis has been in deep sleep. Example7 does not use deep sleep.)

Thanks again,
Paul

[razvandragomirescu]

Correct, it's Example 7 that I've tried, as per your suggestion. The behaviour is the same on both Mac and Windows, both when compiling from source and when loading the binary. Maybe my AGT board is faulty somehow (although that would not explain how/why it works with 1.2.3 but not with 2.1.0)? I only have one, so there's not much I can do about it.

[razvandragomirescu]

BTW, with DIAGNOSTICS=true, it stops at

Calling internalBegin
Powering on modem...

I never get that "AT" command sent to the modem, it never displays that, it just freezes at "Powering on modem...".

[PaulZC]

Thanks again for the diagnostics.

Wow, OK. This is a head-scratcher...

Best guess, some badness is happening when the new code tries to enable the modem via the 'sleep' pin. Why? I did have to change the gnssON and gnssOFF functions in v2.0 because the power glitch issue I fixed months ago on the GNSS enable pin came back again. I wonder if this issue only appear on some pins on some chips. I will try and send you a new binary to try in the next day or two. (It means hacking the IridiumSBDi2c library as the control of the 'sleepPin' is embedded in there.)

Thank you for your patience.

[razvandragomirescu]

I've just installed and run the binary for the iridiumSleepTest, result is below:

Artemis Global Tracker
Example: Get IMEI

Please check that the Serial Monitor is set to 115200 Baud
and that the line ending is set to Newline.
Then click Send to start the example.

Enabling the supercapacitor charger...

Enabling 9603N power...

Calling internalBegin
custom configureSleepPin: sleepPin configured
Powering on modem...

Still appears to freeze on "Powering on modem". Would it help if I mailed you the AGT unit I'm testing on (if you can't reproduce it on your devices)?

[PaulZC]

Hi @razvandragomirescu ,

(Wow - that was fast! I was just typing a message to you but you beat me to it!)

OK. That's very interesting. The code is executing the custom configureSleepPin because we see the custom configureSleepPin: sleepPin configured message.

https://github.com/sparkfun/SparkFun_IridiumSBD_I2C_Arduino_Library/blob/4652dc95da1e2f7425a4005bbe88dd29f3889591/src/IridiumSBD.cpp#L1106

Then we see the Powering on modem... message:

https://github.com/sparkfun/SparkFun_IridiumSBD_I2C_Arduino_Library/blob/4652dc95da1e2f7425a4005bbe88dd29f3889591/src/IridiumSBD.cpp#L1114

But it must be failing in the custom setSleepPin function - or just after it - because we do not see the custom setSleepPin: sleepPin set message.

I'm based in the UK. If you return your board to SF in Boulder, it will get to me but it will take a while. If I'm not trying your patience too much, can we try a couple more custom binaries first? I'd like to understand exactly where the code is failing. I'll upload another binary in a few minutes.

Best wishes,
Paul

Updated files are there now... Thanks!
