It seems there is an error in the documentation, the latest version of the example is made for SDK v15.3.0.

Can you try it with this SDK and see if it works better?

Best regards

You are right of course. For some reason I thought the Thingy would bond, as most BLE devices do.
In that case I expect that the SoftDevice runs out of buffers (memory) when you try to do service discovery and enable notification on 8 devices at the same time.

The easiest way to solve this is to disable scanning on the central when you are doing service discovery. It will slow down the connection time when you have many devices turning on at once, but it will make the process reliable.

I dont think I even bond with the Thingy's how could this still be done ?

Hi
Do you bond with the Thingy's or not?
If you don't bond you have to do service discovery every time you reconnect, and if you try to do service discovery with 8 devices at a time there might be some issues.

hi ToasTer86, thanks for your sugestion, i was able to bring up thingy config service,weather service, userinterface service,motion service and battery service by doing your way.

but now i am facing problem where if i connect all thingy one by one my code works fine. but if i reset my central device and all 8 thingy available at once my central connects to all of them but only enables notification to 3 or 4 of them.. please help me with thi..

I also added support for the Thingy UI service client in the multi link example, but I was too lazy to add support for the other services ;)

I was able to also write to the Thingy52 LEDS using the "Ble_app_multilink_central" if you need any help let me know.

Hey nikunj8086 ,

I am doing a project right now with a nRF52840 and a Thingy 52, my nRF52840 will be the central as well. I am working on the LED button service example now.

If you check the BLE_service files, for example the "ble_lbs_c.c & .h " file you can change the UUID and get some button values from the Thingy52 at least.

Below is what I changed in the ble_lbs_c.h file when working with the LED_button_switch example.

/* OLD VALUES : changed for thingy52 
#define LBS_UUID_BASE        {0x23, 0xD1, 0xBC, 0xEA, 0x5F, 0x78, 0x23, 0x15, \
                              0xDE, 0xEF, 0x12, 0x12, 0x00, 0x00, 0x00, 0x00}
#define LBS_UUID_SERVICE     0x1523
#define LBS_UUID_BUTTON_CHAR 0x1524
#define LBS_UUID_LED_CHAR    0x1525 */

#define LBS_UUID_BASE        {0x42, 0x00, 0x74, 0xA9, 0xFF, 0x52, 0x10, 0x9B, 0x33, 0x49, 0x35, 0x9B, 0x00, 0x00, 0x68, 0xEF}
#define LBS_UUID_SERVICE     0x0300
#define LBS_UUID_BUTTON_CHAR 0x0302
#define LBS_UUID_LED_CHAR    0x0301

this is regarding the " ble_app_multilink_central " example found in the SDK.

With these changes I can read the button state from the Thingy52, although I can't write LED values to the Thingy52 yet. I think that has to do with the data size in the following function uint32_t ble_lbs_led_status_send(ble_lbs_c_t * p_ble_lbs_c, uint8_t status) code in "ble_lbs_c.c"

Unfortunately we don't have client code for the Thingy services for the nRF52 side. All the standard examples assume that the client will be a phone or a PC.

I will check with the team if we are planning to add nRF52 client support, and update my answer once I know more.
