Hi.

Could you share the problem? In case other people have a similar issue.

I'm glad you figured it out, good luck.

Best regards,

Andreas

Thank you for all your help Andreas. We have figured out the problem is in the Bluetooth stack somewhere which is not a Nordic Semiconductor issue. We should be able to track it down from here.

Thanks again,

Rocky

Hi.

Could you provide me with your code, so I can have a look?

I can make this case private in case you don't want your code shared public.

Best regards,

Andreas

Here is the screenshot.

I had only been looking at the advertised data without using the App on the phone. Now that I am using the nRF Connect app, the last digit is wrong there as well.

It is apparent now that the advertised Device Name works fine, but explicit reads of the Device Name fail.

Hi.

Can you compare the names and take a screenshot when you connect to the device on your phone with the nRF Connect Application?

Best regards,

Andreas

Here are the two screen shots. The last digit of the advertised name should be "8" instead of a "7" as the nRF Connect reports.

Hi.

Could you provide me with some screenshots? Of both the phone and nRF Connect Desktop software?

Best regards,

Andreas

Apart from the Device Name, we also encode a byte of flags. Total number of bytes = 28. Here is the breakdown:

FLAGS:

Data type: 1 byte

Data Length: 1 byte

Flags: 1 byte

DEVICE NAME:

Data type: 1 byte

Data Length: 1 byte

Device name: 23 bytes

TOTAL: ble_advdata_encode() = 28 bytes

I'm still confused about how things work perfectly with my android phone, but fail with the nRF Connect software.

Thanks, Rocky

Hi.

What do you encode with the ble_advdata_encode() function apart from the device name?

Best regards,

Andreas
