Mobile App nRF UART is not connecting to Node having Nordic uart service (NUS) integrated into the the nRF mesh

[Gousmodin Somanakoppa]

We have added Nordic Uart Service (NUS) into the nRF mesh code and we created two mobile application.

First mobile application:

- is for nRF mesh provisioning which is fine for us.

Second mobile application to connect to Node and transfer the data using the uart service. In order to do that we use UART of nRF Toolbox and created mobile app. But it is not even getting connected to the node. Can somebody help to get his android mobile app piece of code or tell us the procedure.

Best regards

Hi,

Have you tested with nRF Connect or nRF Toolbox to connect to your device? Just to see if the root cause lies in the firmware or your custom mobile application.

Right now we are checking with nRF Toolbox, but not clear on the approach, whether I would be able to send more than 20bytes using nRF UART after implementation. Because i did test with nRF toolbox UART app from playstore, which is disconnecting immediately after connect attempt. So if I understand, even we use the code of nRF toolbox UART we may face the same issue.

Unfortunately I am not sure why we don't have nRF connect mobile app source code in the github. Because nRF connect mobile app is serving our purpose. Any idea if you can give us the nRF connect source code for mobile app. If not atleast the approach of nRF connect. Because this app is working fine and I am able to send mroe than 20 bytes in a single packet.

Hello,

The nRF Connect is not open source application. It would hardly help you as it's way too complex to be a reference design. But nRF Toolbox -> UART should work equally well. Could you, please, paste the LogCat log from this app during the connection? Do you get any error?
