RE: Asset Tracker V2 not waiting for AGNSS response

Hi Forest,

Michal is not available, and I am looking at your ticket now.

Could you compare your AGNSS process implementation with nrf_cloud_agnss_process function in nrf\subsys\net\lib\nrf_cloud\src\nrf_cloud_agnss.c?

I tested with Cellular: GNSS (nordicsemi.com) sample and add 10 seconds delay between AGNSS receive and process in nrf\samples\cellular\gnss\src\assistance.c, there is no problem with AGNSS injection.

	err = nrf_cloud_rest_agnss_data_get(&rest_ctx, &request, &result);
	if (err) {
		LOG_ERR("Failed to get A-GNSS data, error: %d", err);
		goto agnss_exit;
	}

	LOG_INF("Processing A-GNSS data");
	
    k_sleep(K_SECONDS(10));//wait 10s beween AGNSS recive and process
	
	err = nrf_cloud_agnss_process(result.buf, result.agnss_sz);

Below is the log.

[00:00:02.566,467] <inf> gnss_sample: Requesting A-GNSS data: GPS ephe: 0xffffffff, alm: 0xffffffff
[00:00:05.802,642] <inf> gnss_sample: Processing A-GNSS data
+CSCON: 0
[00:00:15.929,138] <inf> gnss_sample: A-GNSS data processed
Tracking:  0 Using:  0 Unhealthy: 0
-----------------------------------

Disable the following lines in nrf\samples\cellular\gnss\src\main.c to prevent terminal content refresh.

				//printf("\033[1;1H");
				//printf("\033[2J");

Best regards,

Charlie

Hey Michal,

We're using NCS 2.7.0 with the 1.3.6 modem firmware.

Hello,

Could you tell us your NCS and Modem FW versions?

Best regards,
