Hello

GattClient_SimpleCharacteristicWrite sends an ATT Write Request if the value length does not exceed the maximum space for an over-the-air packet (ATT_MTU – 3).

There is a short example to write a 3-byte long Characteristic Value and how the client procedure callback is triggered described in Chapter 5.1.4.4 Characteristic write procedure in Bluetooth Low Energy Application Developer’s Guide

The latest SDK version for KW45 is 25.06, could you help us confirm if you mean another SDK version? As 24.12?

Also, could you help us confirm if the KW45 you are using is the KW45B41Z-EVK or a KW45 custom board?

Best Regards

Luis
