D52QD2M4IA sleep behaviour changed

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

Two months and not a single reply? No one noticed the the D52Q module can't be used as a drop in replacement for the AP2 or N5 modules?

Our apologies, due to some personnel changes this forum temporarily went unmonitored around this time. The TX line on the module is dropping low because the UART is disabled when SLEEP is asserted to save current, although we have not seen this causing any framing issues with usage of the flow control over the UART.
