Thingy:91 not connectable. LED is off but can program

[ImagiSam]

I was working with the Thingy:91 trying to get into into a serial printing state. I tried to updated the modem and firmware using the nrf Programmer. When updating the modem it hangs at 100%. Programming the device seems to succeed but now the LED is not flashing and the Thingy:91 is not connectable

I have tried downloading the following programs but it doesn't run:

• thingy91_ltem_2020-04-29_bc7ade8b.hex
• merged.hex (local based on 1.3.0)
• merged.hex (sourced from here https://devzone.nordicsemi.com/f/nordic-q-a/58484/thingy91-wont-boot-merged-hex-works-on-nrf9160-dk)

It seemed like it was working fine until the modem update which didn't work. 

The other thing is (once it starts working) that if I need to get it printing output to a serial terminal I need to flash:

• thingy91_ltem_2020-04-29_bc7ade8b.hex on the nrf91
• thingy91_nrf52_usb_uart_bridge_2020-04-29_bc7ade8b.hex on the nrf52

And I do that by flipping switch on device, then flip to other and flash and then it should run?

Hi! Glad to hear you got it working.

The next question is that I'd like to get the Thingy 91 printing to serial. Preferably without connecting to it in cloud but right now it doesn't seem to for some reason.

 From the screenshot you attached, it looks like you're getting out debug information from the Thingy:91, so do I understand you correctly that what you say isn't working is the printing of sensor information? 

If that's what you mean, the Asset Tracker sample doesn't print the sensor data to serial so you will have to go into the source code and change that yourself. 

If I misunderstood what you're having trouble with, please clarify and I will help you further. :) 

Best regards,
