MCP and phone visibility

[Ondrej Meca]

Hi,

We are developing weareble with nrf52832 and already made 6 test modules. Everythink works fine except 1 module. This wonderful piece is visible only on PC Win 10 (MCP or our custom testing app). But thats all, this device is not visible to phones or any other (Apple not tested). All modules are identical.

Any suggestions ?

Thanks for help. Ondřej Meca

Ahoj Ondřeji,

Have you tried some radio sniffer (e.g. Nordic sniffer on nRF51 or 52 DK?) These devices are typically well inert to any caching or filtering issues so they see all (or nothing if really broken). Otherwise hard to say what could confuse Android phones so they would miss your broadcasts but MCP on Windows sees it. If you can afford it the reset network setting on test phones (this is easier on iOS devices - although there it wipes all network setting including WiFi and other - while on Android it might depend on HW manufacturer and Android versions/customs, typically wiping data and cache from "BT Share" process is good start).

Cheers Jan
