Hi,
We are using a Jorjin WG7310 (WL1271) radio module in a system running WinCE 6R3. We are experinecing a problem wherein the BT radio shuts itself off after10 minutes of operation during FCC testing. We are using HCI commands to configure the radio for test operation such as continuous TX on one channel, continuous TX with frequency hopping etc. For some unknown reason the BT radio will cease transmititng after 10 minutes of operation. We know that WinCE isn't going to sleep, WZ config is disabled etc. etc. There are no log files of which we are aware that are generated at the time the radio turns off.
The HCI commands to control the BT radio in testing are in script files (.bts files) that run when the BT driver loads. We started with a base example script that we were given. We use SriptPad to alter the last few lines in the scripts when we want to change the power level, modulation, hopping vs fixed frequency and so forth. Everything is working fine except that the BT radio will turn itself off 10 minutes after the script file is run. To get the test going again we must reboot the system. It is not necessary to power cycle, but just reboot to get the driver to load and script to run again.
The attached ZIP contains the 3 script files that we use to enable contiunous transmission at maximum power level in frequency hopping mode - one script for each modulation type. ScriptPad is needed to properly view or edit them, of course. We have other scripts that put the radio into single channel (non-hopping) continuoust transmit modes as well. No matter the script, the radio still shuts off after 10 minutes.
Has anyone else encountered this problem? Anyone have a clue if there could be something in the script files that cause the 10-minute shut down behavior?
Thanks,
Doug
