Hi everyone,
I'm trying to update the ATT MTU with nRF52833 that connects to an IOS app.
For Hardware/software setup, the following is what I'm using:
- Our toolchain is ARM GCC
- Ubuntu
- SDK 17.0.2
- SD 140
I've taken a look at samples BLE_APP_ATT_MTU_THROUGPUT and BLE_APP_UART where the ATT MTU can be updated. The following code is what I implemented to request ATT MTU. However, I wasn't able to update the ATT MTU. I checked the MTU side on IOS app (Xcode software), it showed the MTU is still 23 bytes only when the app connected to nRF52833. Please advise if I need to do anything to change it. Thanks!
