Posting this here because I can't seem to find a reference to the supported Bluetooth version in the documentation. E.g. the nRF52832 can support Bluetooth 5.0, but which version does the Espruino Bluetooth stack support?
Specifically, it looks like my BLE sensor requests the MTU size at 40 bytes during connection setup (using the Bluetooth 4.2 packet extension?) and proceeds to send 37 bytes in each packet. When I try to read from the sensor with the MDBT42Q I only get 20 bytes per packet and the rest of the data appears to be missing.
AFAIK, Espruino only supports 20 byte MTU right now. There is some discussion about increasing it.
