FIRMWARE V1.1.1 i m using this firmware (ABOVE link) in that nRF51822 Beacon v1.1.1/sourcecode/Nrf51_beacon/ble_app_beacon/pca20006/s110/arm/ble_app_beacon_s110_pca20006 open a Ble_app_beacon example in Keil5 and modify in main.c

"#define APP_CONFIG_MODE_LED_MSK (LED_R_MSK | LED_G_MSK)"

instead of that (LED_R_MSK | LED_G_MSK) i put only (LED_R_MSK)

after that compilation is successfully done n generate a hex file n upload that hex file in NRF51822 Beacon. it shows application programmed successfully. but it's not effect on NRF51822 Beacon.

Could you post some code snippets of what you have changed, and a link to the exact example firmware you are using? You should also try debugging, to see if your application is failing.

i try to upload nrf51822_beacon_app example. it's given in Firmware 1.1.0. in that i m try to change the color of LED. because by default in NRF51822 beacon code is there.in that if pressing sw2 then it will blink yellow light. i modify that example and wrote red instead of yellow light. after compile and generate a hex file. upload using NRF51dk kit through NrfGo studio. it will show Programmed Successfully. but it not effect on NRF51822 Beacon. so where i stuck? give me solution.

Ok. thanks Jorgen Holmefjord

Yes, replace BOARD_PCA10028 with BOARD_PCA20006.

hi jorgen Holmefjord, "In c/c++ tab Preprocessor symbol:' BLE_STACK_SUPPORT_REQD S130 BOARD_PCA10028 SOFTDEVICE_PRESENT NRF51 SWI_DISABLE0'." here i want to change here for as per you told " You need to change the board define from BOARD_PCA10028 to BOARD_PCA20006 in the preprocessor symbols settings in your project."

Firmware files is example application for the beacon kit. You do not need to flash it if you use applications from the SDK.

thank you very much. could you tell me about firmfare files,do i need to flash it before softdevice and application.what is the use of that?downloading that also restricted.

Jørgen Holmefjord — Thu, 30 Mar 2017 11:36:53 GMT

You can use any of the examples. You need to change the board define from BOARD_PCA10028 to BOARD_PCA20006 in the preprocessor symbols settings in your project, and potentially the RAM/ROM setting. You need to check which chip version is on your beacon kit, and compare this against the nRF51822 compatibility matrix. The chip on the nRF51 DK (PCA10028) has 32 kB RAM and 256 kB flash.

If you follow the above linked tutorials, you should have a working periheral with your own custom service.

All central examples do scanning and connection to the board. You will have to write your own read function to handle reads from the peripheral. If you want to use notifications, this is used in the ble_app_uart_c example.

hi,

could you please tell me which example exactly can we use for above case(for central,for peripheral) with few modifications.what are the modification to make it central.thank u

Yes, you need to connect the sensor to one of the available GPIOs on the beacon PCB. The pads marked 0, 1, 2, 3, 5, 9, 11, 20, 21, 24 is GPIOs. You should read the BLE tutorials to understand how to do advertising, setting up a custom service and characteristics, and how to use a central to scan for devices. The nRF51822-Beacon kit is not created to act as a central (this is not a typical use-case of a beacon), but it should be able to support any og the nRF51/pca10028 central examples from the SDK, with some minor changes. Note that you will have to adapt the central examples to your specific use-case.

i have this nRF51822-Beacon and i want to connect a touch sensor with nRF51822-Beacon and data of touch sensor send to the another nRF51822-Beacon. and for debugging i have NRF51dk kit. can u tell me it's possible or not? if possible then how it is?

thanks a lot for reply jorgen,

RE: NRF51822 with GPIO PROGRAMMING??????

Jørgen Holmefjord — Fri, 24 Mar 2017 09:24:01 GMT

Yes, the GPIOs are capable of reading high and low values. This can be transmitted through BLE.

RE: NRF51822 with GPIO PROGRAMMING??????

KETAN_PATEL — Fri, 24 Mar 2017 09:13:26 GMT

thanks for reply Jorgen, sensor give output in form of '0' and '1' only. and also one thing that sensor output i want to transmit through BLE it is possible or not?

Hi,

This depends on which type of touch sensor you want to use.

About GPIO example, have a look at this answer.

Best regards,

Jørgen
