Hello,

[quote user=""]Will there be any impact to our already existing BLE service and characteristics ID from this change alone? We have some concerns that if this changes affects the existing service and characteristics ID then it will be a big change on both firmware and our application side.[/quote]

No, there won't be any impact on the existing BLE service or characteristic IDs. As long as these services and characteristics stay the same in your firmware, you don’t need to change the IDs or adjust any application logic connected to them.

[quote user=""]If we implement this way, do we need to update any RAM configuration for softdevice?[/quote]

Moving the device name from the advertising packet to the scan response packet doesn’t require a change in SoftDevice RAM configuration. If RAM or Flash size changes were needed, the build log would indicate this.

[quote user=""]We will use our device with mostly PC and mobile phone (both iOS & Androids) so are there any known compatibility issues of using scan response packet for sending device full name? We have tested with a couple of iOS and android devices on our hands and they seems to work fine however we'd also like to know if there are such cases where compatibility issues might arises.[/quote]

Using the scan response packet to broadcast the full device name is generally compatible with most BLE-capable devices, including PCs, iOS, and Android devices. So, the answer to this question is No; there are no known compatibility issues that might arise
