ble_app_uart with Android failed

[sevstels]

I lost many time and check 3 examples for various versions SDK, in all cases device cant connect to smartphone. Check with appl. "nRF UART 2.0" and last "nRF Connect". Applications detected and show ble "Nordic_UART" device, but cant connect to him.
Also check use "Master Control Panel", but do not see chip:

[22:11:42.2] Loading... [22:11:45.5] No response from master emulator.

But by Putty communication exist.

Chip: nrf51822QFAC and nrf51822QFAA Board: BLE400 IDE: IAR SDK: 6.0 , 10.0 , 12.1 Phone: Samsung SM-J120H, Android ver 5.1.1

Help please fix problem. Working code example or project for IAR and nrf51822.

Hi, Could you provide the SDK version you tested ?

And please provide the hex file after you compile so we can test here.

To test with Master Control Panel on PC, you would need to flash the dongle/DK with the firmware. Please click File -> Programming.

Hi. For last test, I download from nRF51822 product page: nRF5 SDK Zip File ver 12.2.0

Then open examples/peripheral/, retarget IAR projects settings for 51822, and make test for hardware: 1.blinky, 2.rtc, 3.uart. It working well without any problem.

Then open ble_peripheral/ble_app_uart and made same retarget IAR settings. Compilation is well, without any warnings or error. Connect by jumper GND and P30.

Flashing to chip s130_nrf51_2.0.1_softdevice.hex, also successfully. Download to board by JTAG application. Launch to debug. LED blinking with period 2 sec.

Putty print msg: "UART Start!"

Try connect with Android device by 'nRF Connect':

Try connect with Android device by 'nRF UART 2.0':

This - finish... :(

Error 133 is a known bug on Android. You can try to turn off an on Bluetooth, make sure you erase the device (Unpair/Forget this device) in Bluetooth setting. You may also need to restart the phone.

Thank`s. I try it... but no result.

Go to Android Bluetooth Setup menu. 'Nordic_UART' device never be pair here.

1. Shut down Bluetooth interface.
2. Restart the phone.
3. Check connection again.

Result is same: Error 133 here, and impossible use example 'ble_app_uart'.

Have you tried other example ?

Also please try to flash with our pre-compiled hex (if your board has 32kHz crystal).

Please try to test again with SDK v10 and S130 v1.0
