how to working 52832 notification???

[choi]

hello?

I have a problem with the notification project...

In the smartphone app, the status is displayed as notification enabled

However, no data is transmitted due to an error

Can I get a hint of why this is an error?

Thank you for any answers

Hi 

Which SDK version are you using? 

Are you using the ble_app_uart example as is, or have you made changes to the code?

If I understand you correctly you have verified that the error returned is 0x08, INVALID_STATE ?

Best regards
