BlueNRG-1 extended packet length

I am evaluating the use of the SPBTLE-1S module, based on BlueNRG-1 and Bluetooth v4.2 compilant, to interact with iOS. BLE 4.2 specification includes data length extension feature which improves throughput and reduces transaction time. However, according to documentation, only BlueNRG-2 supports BLE extended packet length feature. 


Is it possible to upgrade BLE stack embedded software (library managing the RF part) with a version wich extends the possible MTU size up to 158 bytes?


Thank in advance.
