Peripheral UART Sample on Thingy:91

[winsonrbi]

Hello,

I am having some issues with the peripheral UART sample on the Thingy:91. I used Segger Embedded Studios with the thingy91_nrf52840 as the board, I was able to successfully upload the application to the nrf52840, and I can see it on nRF Connect on my phone but it's not very consistent and it does not seem to actually connect.

I am using an Android mobile device. I uploaded the application using the nRF9160dk as a external debug probe. I'm new to Bluetooth so I'm not sure if I did not upload the application correctly or perhaps I missed a setting for Bluetooth?

Thank you for your time.

Ok

Unfortunately that doesn't help a lot, as error 133 can be multiple different things. Have you done any debugging on the Thingy:91 when you try to connect to it using your phone? It would be interesting to see the debug log here for some further information.

What board have you built the project for when building and flashing the project? You might have to make some changes to the board you're using. Also what UART instance are you using by default. Remember that the communication between the onboard nRF91 and nRF52 also uses UART (UART0 I believe) for communication. You can also check out this case that has a discussion on using the other UART instance on the nRF52 for communication.

Best regards,

Simon
