Thingy91 not Programming

[Balabobot]

Hi,

I follow the instruction to update the https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thingy91_gsg.html 

Updating the firmware in the nRF52840 SoC and following through the USB method.

I don't have the 1.27mm cable to follow through with the external debug probe method.

But, When i select the device with Enable MCU Boot Selected, i get the below error.

19:41:22.451

Target device closed

19:41:44.676

Error while setting up device 0.01: TypeError: Cannot read property '0' of undefined

19:41:44.676

Target device closed.

Hi,

Did you make sure that you pressed SW4 when you switched the Power on for debugging the nRF52840?

Please upload these files directly to this case. I can't see files located at external drives. You can use insert->Image/video/file option in the message reply box.

HI Jared, I do that. for whatever reason, the Thingy91 is not get detected in the nRF desktop.

I have programmed the nRF9160DK and got the data to the cloud using Twilio sim.

Also i have used External debug between the nRF9160DK and Thingy91 and programmed the Thingy91 with nRF52 connectivity bride, nRF9160 with Modem, and application firmware.

Still the thingy91 doesnt work in nRF desktop.

The two uarts exposed in device manager cannot find drivers. I have load the drivers as some in a post in the form told (like nRF 52 CDC driver) no help.

Thing91 UART error when i select the drop down

Both of above drivers did not work.(one form thing91 and the right one from the forum)

nRF9160 DK connected and working

I was able to connect to Thingy91 Uart from mobile nRF connect app over nRF52 BLE

This was the post i was refering to for installing drivers

 Thingy91 USB drivers

Also i got the data in cloud for Thingy91

The problem i have is getting it detected in nRF desktop and LTE monitor.

I have all latest of nRF desktop,programmer, and LTE monitor
