Hi EricI request you to add a feature that master user should get a sms when anyone of the user try to call to the device. Log shall include user phone number, output name and date and time.. pls let me know if possible to work out
It is good one, Interested. Can you suggest the same with WI-FI module instead Bluetooth pls ?
ok thank you for the update. Normally when we send sms to the unit for adding users, unit reply back to the user phone by sms. if the sim doesn't have sufficient balance/airtime, the unit hung there and Green LED up continuously. we need to power off the unit in this case. Can we have any solution for this as let the unit continue for next function if airtime not available?
