AGPS with nrf cloud, Cannot parse schema version: 123

[ActiTAG]

Hello,

I come to you because I wanted to recover the GPS data in my project for that I based on the sample agps, however when I launch my project at the time of the reception of data of the cloud I have this error:

ASSERTION FAIL [version == (1)] @ WEST_TOPDIR/nrf/subsys/net/lib/nrf_cloud/src/nrf_cloud_agps.c549
Cannot parse schema version: 123
This problem does not appear when I run the sample, do you have any idea what the problem is or what I missed?

Hello again Tatiana,

Thanks a lot for your feedback! So, the ASSERT in nrf_cloud_agps.c, which actually is located on line 850, is the following:

version = buf[NRF_CLOUD_AGPS_BIN_SCHEMA_VERSION_INDEX];

parsed_len += NRF_CLOUD_AGPS_BIN_SCHEMA_VERSION_SIZE;



__ASSERT(version == NRF_CLOUD_AGPS_BIN_SCHEMA_VERSION,

"Cannot parse schema version: %d", version);

The binary schema version is supposed to be 1, as defined in nrf_cloud_agps_schema_v1.h:16:

#define NRF_CLOUD_AGPS_BIN_SCHEMA_VERSION (1)

However, the value which comes in from your application via the argument evt->data.msg.buf is obviously 123, which causes the ASSERT.

int err = gps_process_agps_data(evt->data.msg.buf, evt->data.msg.len);

A good starting point might be to check why your application applies this value to the cloud message.

I hope this will help you!

Regards,

Markus
