Display in hex instead of decimal value on nRF Connect

[Jeremy Wu]

Hi,

I am using nRF52805 to transmit string data to the mobile end app "nRF Connect".

I found that sometimes the app will display hex data instead of the expected decimal value for no reason. I used exactly the same code.

Just wondering is this because I forget some constraints so that the output sometimes is not consistent or other reasons?

Can anyone help me with this?

Thanks in advance

Hi Jeremy,

Is it the nRF Connect mobile application for iOS or the android.? Are you running the same code.? In the first screenshot that you shared with the binary data, the application have the Nordic UART service defined where as in the one showing hex data the application has not.. It shows unknown service.. Could you make sure to erase the development board and then flash the application once again..? 

Kind Regards,

Swathy

Hi Swathy,

I am using the mobile app for iOS. 

Yes, I'm using the same code. So this just happens occasionally and can be resolved by rebooting the chip and the app.

I just want to figure out if it is related to my code or just a glitch? Do you have any thoughts about this? Do you think it is because the board didn't erase the flash properly?

Kind Regards

Jeremy
