after you type AT+SD,
whatever you type, it is received on connected radio modules.
I’ve tested and it works.

I’m using mDot 868, Serial Data mode, 0.25kbps data rate.
Channel selection is automatic while using serial mode, right?
I’m still unable to locate issue, one mDot sends packet to other, and other one replies back, whole process taking four seconds, packet is always sent after about two seconds of writing it from COM port at 9600 baud. There may be some timeout parameter that isn’t mentioned in AT command manual.

i used the node id. Each mdot has its own node id of 8 bytes (see the label). this ID is located into the flash.

But that will require handling all packets in user-application layer, Peer to Peer network not necessarily means BROADCASTING each and every packet, I’m not getting why addressing individual nodes at hardware-level is missing.

You have three dots addressed as 1, 2, 3

for 2 to send to 1

AT+NA=1
AT+SEND=DATA
AT+NA=2

I understand that, three are mentioned for example only, in field, there will be many mDots,
I’ve to program same firmware for all slaves, so all slave mDots must have same NA, and other issue is, when each slave will be powered up, it will send a status message to master, slave must have same NA otherwise master will never receive message.

i am developing hybrid system (canbus and rf in peer to peer) and i used one master (display) and up to 4 slaves (RF sensors). I use a my specific protocol. My master knows each address of each sensor. And i have my own ack (ex. 0xAA, ID low, ID high, CS).

Right sir, that simply means there is no way to send Unicast messages, I have one master and around ten or even more slaves, all have same mDot, so is no option for slave to send unicast message destined for master, is troublesome, I’ve used low cost cc1101 chip before, that supports address field also.

AT+NA (Network Address) can be different on each device.
Set the AT+NSK and AT+DSK to the same values.

Then only AT+NA needs to be changed to address a specific dot.

NA is for network address, how two mDots can communicate with each other if set different NA?

[FARRUKH]

Can you please check which AT command to use for configuring mDot’s address? I’m unable to find any in AT command manual.
