Switch from data mode to command mode timeout?

Hi,

When switching from data mode to command mode using the DTR, how much time should I wait for the OK response?

Thanks!

hi
thanks for contacting us, may we know the module type and firmware version you used? thanks

Currently we are using two types:
EC25 - EC25EFAR06A08M4G
EC200S - EC200SEUAAR01A04M16

Thank you!
