CC2340R5 can succeed as a central connection to TI's chip, but fails as a central connection to other devices such as onsemi or cell phone broadcasts.
I used project basic_ble of CC2340 newest SDK and project simple central of CC2642 to test conncetion.
Related results as follows:
2340(central) to 2340(peripheral) succeeded:
2340(central) to 2642(peripheral) succeeded:
2642(central) to onsemi RSL10(peripheral) succeeded:
2340(central) to onsemi RSL10(peripheral) failed:
2340(central) to phone broadcasts(peripheral) failed:
2642(central) to phone broadcasts succeeded:
