Fast FUOTA only possible when using ST BLE Sensor App

[tester]

I am trying to implement the OTA feature of the WB55 into my own app. However, the OTA Update is only successful if every packet is exactly 20 Bytes. I tried doing OTA with the BLE Sensor App and that one is much faster, I suppose the App sends somewhere between 200 and 250 Bytes (probably 240) for every packet. I am using the p2p example firmware.

Now that I can boot to OTA again, I am going to investigate this..

I don't really know what the problem here is, as OTA firmware should be capable of handling packets up to 248 Bytes
