Just to confirm. You are using an nRF52840 as a peripheral in your setup, correct, where the nRF52840 is advertising data to your phone using extended advertising?

1. By "on the nRF side" I mean: If you try debugging the nRF52840 that is advertising while it's running. Does it return any errors when this GATT ERROR occurs in nRFConnect?

2. Can you show me the part of your code (in the peripheral device) where you initialize the advertising and set up the advertising parameters?

Best regards,

Simon

1.Are you seeing an error on the nRF side as well?

Yes.

nRF Connect error is "Error 133 (0x85): GATT ERROR".

2.Can you share a snippet of your advertising_init() function as well, so we can make sure that the extended advertising is set up correctly?

"advertising_init" function is not used.

Which setting's information should I give?

Best regards

Are you seeing an error on the nRF side as well? Error 133 is a generic GATT error and is hard to narrow down without any other details. Can you share a snippet of your advertising_init() function as well, so we can make sure that the extended advertising is set up correctly?

Hi Simonr

thank you for your answer.

I'm sorry I couldn't communicate well.

The problem I'm having is that I can't tell if the problem is with the smartphone or the module.

I wanted to know if there was any information about the phenomenon.

ex) Someone was able to connect in the same environment. Etc..

I have confirmed extended advertising support on "nRF Connect".

However "nRF Connect" issues "Error 133 (0x85): GATT ERROR" as an error.

[quote user=""]there are no event notifications from Softdevice under certain conditions and smartphones are in general error.[/quote]

Can you try to specify what exactly you mean by this sentence? What kinds of errors are you seeing? What exactly is the issue you're having? There shouldn't be any trouble with scanning extended advertisements as long as your phone supports it as well.

Best regards,

Simon
