I have a new D52Q module to replace the aging AP2 and N550 modules i have used previously.
I have found that the RX line returns low when sleep is asserted (previously it idles high regardless of sleep), and I have not seen this behaviour on the other modules. It is upsetting the UART of the micro, causing framing errors. It works ok if I leave sleep deasserted, but i haven't measure the current yet.
Is this a new behaviour, or have I done something incorrectly?
Regards,
Josh
