Hello, when I write the AT commands on Serial Monitor I receive nothing on screen. Everything is connected the same way, but the network status' led shows it is not connected to network (blinks 1 time per second).

pretty simple and easy explanation, Thank you. I have few questions: [1] I experienced a huge delay while send sms which it could reach 8 minutes in sending sms [2] It was necessary to power off the SIM800L and Power on again to keep sending my data as it seems like hung after first long send. [3] Is there away to know the strength of the network so I can start sending my data or keep watching for the proper timing to send? [4] When receiving a call is there a way to save it as any audio file formate? [5] Some countries the 2G network is already disconnected and no more in operation, so is there any low cost alternative for 3G or 4G connectivity [6] in case I use any other microcontrollers i.e. STM, Microchip, NXP will I need to have a special library to get the SIM800L connected? [7] Does it support the Thank you and wish your favorable reply.

[1] I experienced a huge delay while send sms which it could reach 8 minutes in sending sms -> how do you measure it? The network signal strength could be the problem. [2] It was necessary to power off the SIM800L and Power on again to keep sending my data as it seems like hung after first long send. --> there are many factors that could affect that. It could be your power supply is not providing enough power hence it was restarting on itself. It could be that you have weak network signal, etc. [3] Is there away to know the strength of the network so I can start sending my data or keep watching for the proper timing to send? --> AT+CSQ I googled it for you check it from here: m2msupport.net/m2msupport/atcsq-signal-quality/ [4] When receiving a call is there a way to save it as any audio file formate? --> I haven't tried it but I googled it for you and it seems possible, read it from page 335 using the AT+CREC at commands: www.elecrow.com/wiki/images/2/20/SIM800_Series_AT_Command_Manual_V1.09.pdf [5] Some countries the 2G network is already disconnected and no more in operation, so is there any low cost alternative for 3G or 4G connectivity. --> You can easily google it. [6] in case I use any other microcontrollers i.e. STM, Microchip, NXP will I need to have a special library to get the SIM800L connected? --> No need, SIM800L uses UART serial interface to be connected to a microcontroller. So you may simply send the necessary AT commands. [7] Does it support the --> Incomplete sentence, I cannot answer that. Hope this helps you. Cheers.
