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.

Dear Adriana Albert,

as reported in the documentation, only BlueNRG-2 supports the BLE extended packet length and there are no firmware updates available to enable this feature with BlueNRG-1 too.
