I have been using a BV6000 for ever to measure my blood sugar via NFC. On the BV6000 the sensor can be up to 40mm away from the phone and anywhere withing 30 mm of the centre of the back.
I recently got a BV8000 to replace it with and the NFC range is terrible. It has to be exactly in one particular location just above centre and within 10 mm of the back to work. Is there any way to make the NFC more sensitive?
The current OS is: v0.1_20170803_20180307-1950
I cannot change the OS either up or down using manual update and OTA updates are current.
