BLE : Ignoring data for unknown channel ID 0x003a

[DipeshParikh_]

Hello,

My BLE peripheral code works fine with Android devices, but it is failing with iOS devices. I am encountering an error message: "Ignoring data for unknown channel ID 0x003a" after establishing the BLE connection. Additionally, the peripheral fails to send data to the central device.

Could anyone assist in resolving this issue?

Your help would be greatly appreciated.

Hello,

The message "Ignoring data for unknown channel ID 0x003a" is safe to ignore. I don't know exactly what it is, but I guess it is some proprietary check that the iOS devices use to determine whether the connected device is an apple device or something. I see it all the time, but it doesn't do any harm. 

Other than that, you say it fails to send any data. Can you please let me know what you are seeing? Have you tried to monitor the logs from the nRF? Do you see any logs at all? What sample are you using?

Best regards,

Edvin

Hello,

Thank you for your quick response.

When I connect my peripheral device to the nRF Connect application and enable notifications for the service, it fails to send data in this situation, although it works fine with the Android device.

What happens when you try to send notifications (data) from the nRF to the iOS? Does the log from the nRF say anything when it fails?
