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.

Hi

I assume this is the peripheral_UART sample project you have flashed onto your Thingy:91?

Can you upload the log from nRFConnect on your phone when trying to connect to the UART peripheral? You should be able to see a disconnect or "failed to connect" reason in the nRFConnect log.

Best regards,

Simon
