Hello Joao Filipe, have you made any progress on this, or do you still want me to look into it?

Best regards,

Simon

A huge portion of the support team is currently on Christmas vacation and you may experience delayed answers. Most of the staff will be back 6 of January 2020 and you can be sure to get an answer shortly after that.

Best regards,

Hi Simon, if you please so and if wasn't boring you, I would appreciate that.

Try adding a 128 bits UUID to the advertising packet in the nRF52840 device like Jørgen has done in this ticket. If you want me to create some examples (on both the nRF9160 DK and the nRF52840 DK) that demonstrate this, please tell me.

Best regards,

Simon

Hi.

I tried what you told me, but didn't worked.

So, since I didn't figured out what was my UUID to advertising, i tried to connect with the service UUID directly. I tried this one:

#define BT_UUID_TMS
BT_UUID_DECLARE_16(0x1620)
...
...
...
err = bt_scan_filter_add(BT_SCAN_FILTER_TYPE_UUID, BT_UUID_TMS);

I was able to get connection with both boards. I added some code with leds like If the nrf52 connected to any device, led2 lights up, to see if I was able to get connection. The LTE Link Monitor also wrote a message saying that I got connected.

But I tried to alter from the 16 format to 128 but I couldn't get a connection. I use the UUID base like in the white image upper with the 0x1620.

#define BT_UUID_TMS                                                            
   BT_UUID_DECLARE_128(0xAA, 0xC2, 0x1B, 0x44, 0xDB, 0xA8, 0x1B, 0x96,         
    0xEE, 0x7F, 0x37, 0x57, 0x16, 0x20, 0x26, 0x2D)

With that code, couldn't get a connection. At my viewpoint those codes are the same, no? If don't can you help me.

You should add the BT_UUID_THINGY (=0x42, 0x00, 0x74, 0xA9, 0xFF, 0x52, 0x10, 0x9B, 0x33, 0x49, 0x35, 0x9B, 0x00, 0x01, 0x68, 0xEF) to the advertising packet before calling advertising_init() (in the device taking the Thingy:52 role), like it's done here.

Best regards,

Simon
