Hi @Giang... I am trying to do the same thing. Send string using multilink + multiperipheral. Did you resolv this question? Can you help me?

Hi Jørgen , If i want research about NRF52832 , I must read Core Spec v4.2 or Bluetooth Core Spec v5 ?Thank you !!!

If you hit the error handeler, a non-zero error code have occurred. You can check the details of the error in the info struct. See this post for more details.

Hi Jørgen , May I ask you ? When I modify ble_uart_app and ble_uart_app_c , I often encountered an error NRF_BREAKPOINT_COND in app_error_weak.c file when I debug . But I dont know what it is . Can you show me how to solve it ? Thank for help !!!

You can find some information about BLE in our tutorial sections:

You can also read about BLE in this blog post.

All information about the nRF52832 IC can be found in the infocenter.

Hi Jørgen , I have to write a report about BLE and chip NRF52832 . I need to find out about the operation , the connection , the transmit data , the receiver data... everything related to BLE and NRF52832 . Can you recommend some document that could help me? Thank very much !!!

Hi Jørgen , I understand what you mean I will have to including ble_nus_c to multi central project and including ble_nus to multi peripheral project . Because I dont have much time for it , Can you add my skype : truonggiangbkak58@gmail.com . Thank very much !!!

ble_lbs_c and ble_lbs implements the LED Button Service client and server, and cannot be used for transmitting strings. You should use ble_nus_c and ble_nus, as used in ble_app_uart_c and ble_app_uart examples. You can find some threads about including this in multiperipheral and add multilink support to the ble_app_uart_c examples here, here and here.

Hi Jørgen , I found file ble_lbs_c at central project and ble_lbs at peripheral project . I think I can modify it for send string between central board and peripheral board . Please tell me the direction is correct ?? Thank you for the help !!!

Hi Jørgen , I want to connect multi central with multi peripheral , then send string between them . If not use NUS , is it imposible ? Or Can I combine multilink with NUS , is it impossible ? Please give me an advice . I do not have much time !! Thank very much

If you want to sent strings, you can use the Nordic UART Service (NUS). We have examples for both Peripheral and Central, but these does not implement support for multilink. You will have to study the multi-link central and multiperipheral examples, and transfer the principles used to the NUS examples.

Thank Jørgen , It worked . If I want to send and receiver the string between peripherral board and central board ,I need to care about the function ? Thank !!!

What you are experiencing is most likely due to this note in the documentation of the ble_multiperipheral example:

Note that you can also use the BLE Multi-link Example as Central. However, the multi-link example accepts all peripheral connections, so the Peripheral will connect four times to the same Central. As a result, you will see four indications for each event.

You will have to modify the multi-link cental example to check if the address found in the advertising packet is the same as the one of an already connected device. I have attached a modified version of the multi-link central example from SDK 14 that should support connection to multiple examples running the multiperipheral example, in my above answer.

Hi Jørgen , I can connect 1 peripheral to multi central and conect 1 central to multi peripheral .But I cant connect multi peripheral to multi central at the same time . I not sure it is posible . Can you give me advice ? Thank

Hi,

Please have a look at the Experimental: BLE Multiperipheral Application Example and the BLE Multi-link Example in the SDK.

[EDIT 16.10.2017]: Attached modified example from multi-link central example to support connection to multiperipheral example: main.c

Best regards,

Jørgen
