When trying the ble/heart_rate.toit example (https://raw.githubusercontent.com/toitlang/toit/master/examples/ble/heart_rate.toit) I'm getting the following errors:

@MikkelD

do you have any idea before I start debugging?

It's properties & BLE_GATT_CHR_F_READ that is false and leads to the 'INVALID_ARGUMENT'.

I think that 'if' was missing checks for notify and indicate.
I uploaded a PR.

Fixed in SDK v2.0.0-alpha.83 shipping in Jaguar v1.9.22 and Artemis v0.6.1.
