Hi,

I have found the following link. It looks like the error 133 raised by BLE Scanner is due to the App itself - not to the code running on the CC2640R2F. Based on the link, it sounds like the mobile app has been updated lately. Could you please check if updating the mobile app could help?

Best regards,

Then it means that the board cc2640r2f will not send the code error 133, but it will be the mobile phone itself.

Am I understanding this right?

Hi,

The event that will cause this error 133 to occur. Is there any cause for you to know?

I try to tested more and found that If I bring Bluetooth close to your mobile phone and connect it several times, I will find the code 133 every once in a while. But if I put Bluetooth away from your mobile phone and try to connect, I will find that the code 133 is often found. Is it possible that Noise may have resulted in this code 133 occurring.

Thank,

Hi,

To be honest, I don't know. I am only a user of this App and cannot provide any support for it.

That being, your theory is definitely possible. The App may be a be sensitive to packet losses.
