GATT S110 MTU size

Samra

Hi again, I posted earlier in another post that my writeCharacteristic is responding with status 6.

Details: Android version: 5.1 Nordic device: nRf51822 S110

I have increased my device mtu size to 512, same needs to be done at device end. Is it possible in S110 or is there an alternate way?

    @Samra: Could you provide more information about the issue you have ? Error 6 means GATT_REQUEST_NOT_SUPPORTED. Are you sure you used the correct handle ID and the characteristic support write request ?

    I assume you increased MTU size to 512 on Android side. On the nRF51 is't not possible to change the MTU from 53. Start from S132 v3.0 (for nRF52) you can increase the MTU to maximum 512.
