This guide shows you how to generate and provision new nRF Cloud certificates for your Nordic Thingy:91 or nRF9160 development kit.
Pre-compiled application firmware for Thingy:91 can be found under the Thingy:91 download page, the included thingy91_at_client binaries (v0.2.3 and later) supports the needed long AT commands. A guide on how to update the Thingy:91 FW can be found here.
Pre-compiled application firmware for nRF9160-DK can be found under the nRF9160-DK download page and also supports the needed long AT commands.
To download new certificates go into the account view on nRF Cloud. Then input your device IMEI number and PIN/HWID found on the label on the PCB into the Device Certificates card. HWID for nRF9160-DK and PIN for Thingy:91.Then click the Download Certificate button.
The device needs to be deleted from nRFCloud before the new certificates will work.
Go into the account view on nRF Cloud. Then input your device IMEI number and PIN/HWID found on the label on the PCB into the Reset a Device card. HWID for nRF9160-DK and PIN for Thingy:91.
Then click the Reset Device button.
Well, after 10 minutes, it actually got a POLLHUP, followed by a reboot. Then after around 5 minutes it connected via first PDN and then LTE! :-)
@luposlip You should create a new thread for your problem.
I even got myself a IoT sim card from the largest national provider of IoT SIM cards. Still no luck :-(
Update: I've now tried with the SIM from my mobile phone (LTE). I'm not sure if that should work or not, but it doesn't.
I have an early nrf9160 (PCA10090 v 0.8.2).
Finally after around 13 minutes, this is output to the log, and the LTE icon turns solid gray (in the LTE Link Monitor app):
[00:12:09.635,650] [0m lte_lc.parse_nw_reg_status: Network registration status: 2 [0m
[00:12:09.925,964] [1;31m lte_lc: Could not parse AT+CEREG response, error: -11
[0m[00:12:09.934,051] [1;31m lte_lc: Could not get network registration status[0m
[00:12:09.944,763] [0m lte_lc.parse_nw_reg_status: Network registration status: 4[0m
[00:12:09.993,286] [0m lte_lc.parse_nw_reg_status: Network registration status: 4[0m
Then after a bit longer, the LTE stays gray, but the signal strength indicator shows 3 out of 4, while the Current Band shows N/A.
The Chart shows some activity too. A green line appears showing reference signal power. But at the same time an event (in the chart) says "No suitable cells in tracking area".
I'm living in Denmark, where the iBasis website says there's national coverage.
What's going on? Thanks in advance.
