Hi.
I use nrf51822 rev.3 build number CEAAE00(0x0079) package is WLCSP. Before I got a experience already develop wearable device using rev.1 chip. And that board work perfect with dongle and smartphone.
Recently I changed my ic rev.1(QFN) to rev.3(WLCSP) and Softdevice 8 and SDK is v8.1.0. and then this chip is work properly with USB Dongle(PCA10000). but not work(not scanable) with smartphone(Android and also iphone).
how can i scan my device in smartphone?
Summarize..
- recently changed SD 5.2.1 to SD 8
- also change sdk 5 to 8.1.0
- chip revision change 1 to 3
- scan and connect working with dongle
- but not scan in smartphone(iphone, android) also not connectable
- also example(sdk\examples\ble_peripheral\ble_app_uart) that include in sdk is not work too.
