It's connected and running well now. I had to put the unit in a better location to get it to connect. Thanks for your help.

Hi Fred,

According to nRF9160: Asset Tracker v2 — nRF Connect SDK 1.9.0 documentation (nordicsemi.com), Light Blue means the application is running on active mode. This information is not enough for debugging the issue. If you connect your device to Link Monitor, it will print out more debug information like below. We would be able to find more clues for this issue.

I finally was able to Activate a SIM card. The SIM card is now present in nRF Cloud.

However, I cannot Add LTE Device.

The LED on the Thingy:91 is blinking Light Blue.

What could be the issue?

RE: Thingy:91 SIM Expired

Hi Fred,

Thanks for your update.

Can you try the solutions mentioned below?

NRFCloud - New iBasis Sims are 19 digits, the platform only allows for 18 - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

Best regards,

Charlie

I loaded thingy91_asset_tracker_v2_ltem_2021-12-15_cfedfdfa.hex into the Thingy and am now able to use the LTE Monitor to see activity and give commands.

I have received the replacement SIM from iBASIS for the expired SIM that was shipped with the Thingy. However, I again am unable to activate the SIM card, this time due to the ICCID on the new SIM is 20 digits, but the "Activate SIM Card" form in nRF Cloud only accepts 18 digits. Again, what to do?

Hi Fred,

[quote user="fackbell"]I'm not able to do anything in the monitor until I get my replacement SIM?[/quote]

The AT command is not related to SIM card. It is the modem core that responds back current state.

[quote user="fackbell"]when I try programming the "serial_lte_modem_2021-12-15_cfedfdfa.hex" file, I can no longer see/select the Thingy either in the programmer or the LTE Link Monitor.[/quote]

This is probably the reason you did not see the response from AT command because you did not successfully program this serial LTE modem application firmware.

Following Updating firmware through USB guidance section 5 Update the nRF9160 SiP application, do you mean you have a problem at step c? but it is exactly the same action as the modem firmware update you did with "mfw_nrf9160_1.3.1.zip". Please double-check and provide more details about your failure if the problem still exists.

Best regards,

Charlie

I programmed the 'thingy91_nrf52_connectivity_bridge_2021-12-15_cfedfdfa.hex" file (the only one I didn't try) and then the "mfw_nrf9160_1.3.1.zip" file. After cycling power, I can now select the device in the programmer and the LTE Link Monitor, which wasn't showing up previously. LTE Link Monitor shows that the Modem port is opened, but none of the AT commands work. I'm assuming this is because my Thingy was shipped with an expired SIM card, so I'm not able to do anything in the monitor until I get my replacement SIM? Let me know if this assumption isn't correct. I've attached a screen shot of the monitor.

Also, when I try programming the "serial_lte_modem_2021-12-15_cfedfdfa.hex" file, I can no longer see/select the Thingy either in the programmer or the LTE Link Monitor.

Ok, I am not sure what happens and what you mean by "the device is not available in any of the apps." Let us do some debugging together to save your bricked device.

1. To save the bricked thingy91, follow the Updating firmware through USB guidance to reprogram the nRF52840 System on Chip (SoC) application firmware(latest is thingy91_nrf52_connectivity_bridge_2021-12-15_cfedfdfa.hex), the modem firmware on the nRF9160 System in Package (SiP)(mfw_nrf9160_1.3.1.zip), the modem firmware on the nRF9160 System in Package (SiP)(serial_lte_modem_2021-12-15_cfedfdfa). Please share me your log file generated by the Programmer app. You should get something like this:

devzone.nordicsemi.com/.../2022_2D00_02_2D00_11T09_5F00_44_5F00_11.593Z_2D00_log.txt

2. Connect the thingy91 with LTE Link Monitor app, you should see the following output with AT+CFUN?

AT+CFUN?
+CFUN: 0
OK

Best regards,

Charlie

I tried both serial_lte_modem_2021-12-15_cfedfdfa.hex and thingy91_at_client_2021-12-15_cfedfdfa.hex files from the img_fota_dfu_hex folder as suggested with the same result which is after writing the file and cycling power, the device is not available in any of the apps. The LED's cycle between a short green and a long red. So, for now this device is a brick. Let me know what else I can do to get this up and going.

Hi Fred，

[quote user=""]I'm I able to use my own SIM card from my phone? [/quote]

You need a SIM card that specially supports LTE-M/NB-IoT network. SIM used by mobile phones normally does not have support on Cellular IoT networks.

[quote user=""]LTE Link Monitor can connect to the UART, but there is no activity and no response from any AT command.[/quote]

You need to program either of the following sample firmware in order to run AT commands.

nRF9160: Serial LTE modem — nRF Connect SDK 1.8.0 documentation (nordicsemi.com)

nRF9160: AT Client — nRF Connect SDK 1.8.0 documentation (nordicsemi.com)

[quote user="fackbell"]I loaded one of the hex files from the img_app_bl folde[/quote]

According to CONTENTS.txt, img_fota_dfu_hex/ is the correct choice if you do DFU through USB with the bootloader. When you need to reprogram the whole firmware including the bootloader with a programer like J-LInk, the firmware in img_app_bl/ is the correct choice.

Best regards

Charlie

I now have another issue with the Thingy. After putting the unit into MCUboot mode by pressing SW4 while switching SW1 to the ON position, I loaded one of the hex files from the img_app_bl folder (doesn't matter which one, I've tried a number of them) and wrote it successfully to the device. However, when I cycle power, none of the apps (Programmer, LTE Link Monitor, Trace Collector) see the device any longer. The device was visible before I wrote the hex file for the first time. The LED comes on first as blinking green and then after a few minutes goes to blinking blue. I am able to program hex files in MCUboot mode, but when it's not in that mode none of the apps see the Thingy.
