Steve, happy to hear you were able to get the Thingy:91 visible in the device list.

Can you please provide the nrfjprog and jlink version you are running (nrfjprog -v), and what version of the nRF Connect for Desktop?

OK My Steps

1) Bring up rfConnect

2) Run the programmer

3) Push sw4 turn on power

4) Select nRF52840 in select drop down

5 Drag thingy91_nrf52_connectivity_bridge_2021-03-04_8e8c6089.hex to programmer

Hello,

[quote user="spope"]Also if I power on thingy with sw4 pushed when I power up I see the board in the programmer, But if I do this with sw3 pushed on during power up I see nothing in the programmer.[/quote]

It sounds like you need to program the nRF52840 with the newest connectivity bridge. Did you try this? You can put the device in serial recovery mode by pressing SW4 while powering the Thingy:91, which is probably why you see this device in the programmer app. Please follow my last comment:

[quote user="oys"]If so, can you please download the latest precompiled firmware package from the Thingy:91 downloads page, and then update the nRF52840 with the connectivity bridge .hex file (img_fota_dfu_hex\thingy91_nrf52_connectivity_bridge_2021-03-04_8e8c6089.hex).[/quote]

Kind regards,
Øyvind

We I turn on the thingy91 I do not see any LEDs turning on. I check the battery voltage and it is good at 4.1 volts.

Also if I power on thingy with sw4 pushed when I power up I see the board in the programmer, But if I do this with sw3 pushed on during power up I see nothing in the programmer.

We I want to do load the tracker app to the thingy board with the nrfconnect programmer but I cannot get the program to see the board.

HI Steve,

Can you please clarify what you are trying to achieve? Are you trying to program the Thingy:91 using MCUboot (USB)?

If so, can you please download the latest precompiled firmware package from the Thingy:91 downloads page, and then update the nRF52840 with the connectivity bridge .hex file (img_fota_dfu_hex\thingy91_nrf52_connectivity_bridge_2021-03-04_8e8c6089.hex).

You may also use the nRF9160DK to update the FW, just remember to set SW2 to nRF52. Note that when you press SW3 or SW4 while turning the Thingy:91 on, you are putting the device into serial recovery mode. This is only needed when a external debugger is not present. The nRF9160 DK is able to program the Thingy:91 as an external debugger if an external debugger probe is connected between the "Debug out" on the nRF9160 DK and "Debug in" on the Thingy:91.

Kind regards,
Øyvind
