Great that you got it working. And thanks for adding an answer :)

Thanks the services works now. The error was that I initialized both cccd with NULL instead of the second with &cccd

Ok, Thanks the services works now. The error was that I initialized both cccd with NULL instead of the second with &cccd.

Hi, I changed the main to resolve some errors. The issue is almost the same. I get the 0x3401 from the sd_ble_gatts_hvx(). I read in the forum, that this is a cccd problem. But I don't get the BLE EVT (SYS_ATTR_MISSING). Through debugging I realized, that no matter which of these two services I am calling. The BLE_GAP_EVT_CONNECTED and BLE_GATTS_WRITE triggers always the same state maschine in this case (positioning). Maybe I am overwritting the cccd during the initialization.

Thanks

What do you mean by now? Did you change anything? Is 0x3401 returned from sd_ble_gatts_hvx()?

Ok, it's weird, now im getting the error 0x3401, on a consitent base. With sd_ble_gatts_set then I get the invalid state error...

I used Keil yes.

Which IDE did you use? Keil? I use eclipse. Maybe there is a memory issue. I will check it later and report the answer. Thanks for checking the services.

I tried to reproduce your issue with the files in the repo, but I can't. Both sd_ble_gatts_hvx() seems to be working fine. Maybe you should investiage the arguments given to sd_ble_gatts_hvx() when you get the error?

Thanks for your help. I created a githup repository. I think this is the best way

github.com/.../ServicesnotworkingTogether

When I comment out services_init() in line the service positioning works. Otherwise only the inertial service works. I am using the SDK_v8 and the Softdevice 130

The sd_ble_gatts_hvx() of the second added service inconsistently returns 0x00000004 NRF_ERROR_NO_MEM, 0x00000005 NRF_ERROR_NO_MEM, and 0x00000007 NRF_ERROR_INVALID_PARAM? Sounds very strange. I'm not sure what could cause this. Would it be possible for you to upload a complete project that exhibits the behvior? Please also include what SD and SDK versions you are using.

Hi,

I added my sd_ble_gatts_hvx() calls. With the app I can see all services.

Are you able to discover both characteristics with for example Master Control Panel? Are you sure you are calling sd_ble_gatts_hvx() with the correct parameters? It returns various error codes?
