I’ve shipped test build 345 onto TestFlight this evening.

This build supports MS1, MS1/Extra and MS2/Extra having been tested against my own ECUs.

MS2 testing has revealed a weakness of the Bluetooth interface, compared to WiFi and I’m still investigating ways around it. For the moment though I’ve put a workaround into the app to compensate. It does mean though that it’s unlikely that the same Bluetooth device that you use for iOS can be used for TunerStudio or similar.

There is a limitation in some of the modules that prevents the module transmitting a block of data that’s more than 500 bytes long at 115,200 baud. For MS2 and MS2/Extra this is an issue as the data pages that the app loads at startup are 1024 bytes each. This certainly applies to the HC-08 modules and I will test the HM-10 module, hopefully, in the next couple of evenings to see if that has the same limitation.
