Write command request is not displayed in the nRF Connect Android app

[Naven Suresh]

I am using 3 mobiles for testing 

1. One Plus 6

2. Samsung Galaxy Note 8 or Google Pixel

When I connect my hardware with #1 phone and send some data from the nRF Connect mobile app, I am getting the response and it is displayed in the nRF Connect App (Client log)

But when I send the same data from #2 phones, the response or the bytes received are not displayed in the nRF Connect App (Client log)

Hi Naven, 

There could be a chance that the phones #2 was not using write with response. Or the response was not propaganded to the app. Could you please capture a sniffer trace to see what actually happens over the air ? 

Could you take a screenshot in both tests with Phone #1 and Phones #2 ?

Hi Hung Bui,

Thanks for your quick support, You are right in the Configure GATT server option --> Write permission was not enabled in the characteristic

Once after enabling, it is working in #2 phones also

Thanks!
