Hi,

Receive buffer size default is 1024 when HERE is used. If this is not enough, it can be increased. Please have a look at CONFIG_LOCATION_SERVICE_CLOUD_RECV_BUF_SIZE Kconfig option.

Best regards,

rest_client: Receive buffer too small, 1026 bytes are required

I'm guessing HERE returns a "404 position could not be retrieved... yaddayadda", it's a rather long message (1026 bytes in this case). The location default buffer is 512 1024 (at least for sdk v2.6.1), which results in the error message you see there.

You can fix this error by setting the buffer size larger, e.g

CONFIG_LOCATION_SERVICE_CLOUD_RECV_BUF_SIZE=1152

This is at least fixes that error, but it'll just let you see the full error response from the HERE API, which happens when you try to get cellular position with NB-IoT cells.
The nRF HERE implementation isn't fully up to date, it's providing cell data as "lte" objects, regardless of modem mode. HERE API has been updated and has support for separate "lte", "lteCatM" and "nbiot" objects now.

(EDIT: corrected default buffer size to 1024, as per dejans's comment below)

Hi,

Is your application based on any of our existing samples?

Which NCS version do you use?

In the location library requirements, you can find information how to update nRF Cloud certificates. For required credentials and authentication you can look at location service accounts.

Could it be possible that the certificate for HERE has expired and if so how do we renew it?

The firmware hasn't changed in a long time, so no changes made. It is running on Segger V1.9.1

My thinking is that it may be Here

Hi,

Can you provide more information about your application?

Have you made any changes to your application in the mentioned timeframe (last 8 days)?

Best regards,
Dejan
