We are using nRF51822 and is considering update to SoftDevice S130.
There are two things we currently investigation:
1. Support security.
2. Increase MTU (possible)
We notice that GATT_MTU_SIZE_DEFAULT is 23 w/ S130 and NRF_SD_BLE_API_VERSION is 2.
There are two things need to be cleared:
1. Is there hardware restriction which prevents GATT_MTU_SIZE_DEFAULT to be increased beyond 23?
2. Is there any side effect if application modify GATT_MTU_SIZE_DEFAULT and NRF_SD_BLE_API_VERSION
to change stack's behavior? We want to know if S130 stack can work with this kind of modification?
