uBlox Sara-U270 comm interface timing out

[Fresh (CHING-HSIN, LEE)]

Hi Adam,

The question is duplicated in this thread.

FreeRtos on nrf52 with BG95M2

Hi Ukhan717, The AT commands of BG95 and BG96 are very similar. We have tested on the BG95 EVB board with firmware version BG95M1LAR02A02_01.002.01.002. After applying the patch below, the windows simulator demo project of BG96 can run with this BG95 EVB in our environment. We suggest updating the BG95 firmware to the latest. In the past we did see more incompatibility between BG96 and BG95. But after updating firmware the difference narrowed, and we were able to make it work by just apply…

It could be the comm interface problem.
Detail reasons and patches are provided in previous thread.

We can do the followings to help locating the problem:

1. Use FreeRTOS windows simulator as a comparison.
2. Add more debug log to indicate the timeout reason.

A patch to reproduce this problem on windows simulator is also provided to help understanding this problem.

Let’s move the discussion in previous thread.
Please provide more information for discussion.
