hello ctchong .,

is it possible to subscribe to temperature value or any other value from the thingy 52 rather than flip state as stated in the sample of https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/lte_ble_gateway/README.html .,

Could you please provide the best way to subscribe to temperature value from the example

Hi,

You can only have one discover process active at the same time, as described in the documentation (http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/include/bluetooth/gatt_dm.html#api-documentation)

Are you releasing the data before calling dm_continue?

I get the following error from PUTTY.

***** HARD FAULT *****
Fault escalation (see below)
***** BUS FAULT *****
Precise data bus error
BFAR Address: 0x50008120
***** Hardware exception *****
Current thread ID = 0x20020154
Faulting instruction address = 0x6e2b0444
Fatal fault in ISR! Spinning...

Is this behavior consistent? Could you post the sequence you are performing?

Kind regards,

Håkon

If svc_uuid is set to NULL, all services may be discovered. To process the next service, call bt_gatt_dm_continue.

If I try to discover all services using NULL,

err = bt_gatt_dm_start(conn, NULL, &discovery_cb, NULL);//
if (err) {
printk("Could not start Motion service discovery, err %d\n", err);
}

I get the following error from PUTTY.
