Hello,
I'm using a nRF52 DK to test BLE communication with another microcontroller. What I need to test is the nRF52 pairing with another brand microcontroller, send a data stream and close the connection.
Could you please tell me which example from the Bluetooth samples list I can use for starting?
Thanks for your attention.
Regards,
The Bluetooth: Central / Heart-rate Monitor sample should be a good start.
Hello haakonsh,
Thank you very much. I've reviewed this example and it is supposed to connect with the first device with an strong signal. Is there a way to force the board to connect with the device with a given MAC address?
Hello Vidar Berg,
Do you have any hint to solve this issue? Thanks for your attention.
Hello,
Do you have a link to where the BT service on the ESP is documented?
Hello,
Yes. It is documented here.
Hello,
It's difficult to troubleshoot this without having the ESP to test against. But it looks like it worked better before you made the changes I suggested. Can you revert back to when the discovery worked? Then swap the TX and RX UUID (BT_UUID_NUS_TX_VAL & BT_UUID_NUS_RX_VAL) and see if that improves anything. Doing this should fix the warning you got here:
[00:00:30.978,515] <err> nus_c: bt_nus_handles_assign: Missing NUS TX CCC in characteristic

Hello,
I've rolled-back to the previous version and I don't have the warning you've mentioned. Nevertheless, the discovery service is not found:

On the ESP32 side I see that both terminals are connected but there is no data transmission.
ilHello,
I have declared the UUID as follows:
#define BT_UUID_NUS_VAL \ BT_UUID_128_ENCODE(0x0000FFFF, 0x0000, 0x1000, 0x8000, 0x00805F9B34FB) /** @brief UUID of the TX Characteristic. **/ #define BT_UUID_NUS_TX_VAL \ BT_UUID_128_ENCODE(0x0000FF02, 0x0000, 0x1000, 0x8000, 0x00805F9B34FB) /** @brief UUID of the RX Characteristic. **/ #define BT_UUID_NUS_RX_VAL \ BT_UUID_128_ENCODE(0x0000FF01, 0x0000, 0x1000, 0x8000, 0x00805F9B34FB)
Now the discovery service seems to work better:

It seems like some data is being transmitted but in a format not supported by the ESP32. Nevertheless, I'd like to understand why I still have errors when establishing the connection:

Hello,
Can you please capture a sniffer trace of when you are pairing with the phone and when you are attempting to pair with the nRF. This should give us a better idea of where the problem is.

Hello,
I've followed the guide to install the sniffer tracer in both the computer and the nRF52. Nevertheless, I can't see the interface in Wireshark:
In View --> Interface Toolbars I have the 'nRF Sniffer for BlueTooth LE' option enabled but the nRF52DK doesn't seem to be detected even if I was able to flash it with the programming tool. Is there any step I'm missing?
Did you get the expected output at step 3 here:
?
