hi

i am using two dongles.one would be sending sensor data from gpio to other through ble.i need a example code for those two.could you please tell me which example i can use?

thank you in advance

Hi,

I would recommend that you go through the BLE tutorials about Advertising, Services, Characteristics, and central. This will give you a great introduction to how to do advertising, create your own service and characteristics, and to scan and connect the peripheral using a central.

In our SDK, you can also find many examples for both peripheral and central. For reading GPIOs, you should have a look at the GPIO abstraction documentation.

Best regards,

Jørgen

i tried ble_app_uart from sdk 8.0.0 in pca10028 and it is working.but i want to run it in pca20006.i changed device to 51822 & board to pca20006(in preprocessor settings) & ram settings to 0x18000,0x28000(size),rom to 20002000,8000(size). but still not working. is it possible? what else i should change?

From what you write, you have swapped RAM and ROM settings. They shold be like this:

IROM1: Start: 0x18000, Size: 0x28000
IRAM1: Start: 0x20002000, Size: 0x6000

If you do not have the latest revision of the beacon kit (1.3.0 containing CFAC chip with 32 kB RAM), you also need to reduce IRAM1 size to 0x2000.
