Bro I want to learn with you but I don't have money 😣

i have a issues, i have a four xbee´s, one coordinator and three end devices, so i want to read analog data from the end devices and send data temperature to coordinator, the coordinator with arduino uno, but the reason of my problem is i have a xbee series 1, yup, series 1 digimesh 2.4, so i change the firmware to 802.15.4, i read manuals, i see your video, but i can not communicate

Those endpoint will turn on/off LEDs.

Excellent site. I wanted to pass on a solution I recently came across. Scenario = IPSEC VPN: 1841->NAT->Cradlepoint IBR600 v5.0 -> LTE -> ASA v8.2. Problem= NAT-T failure. Debug=retransmitting phase 1 MM_KEY_EXCH. my_port 500 peer_port 500 (R) MM_KEY_EXCH. The 1841 had "crypto ipsec nat-transparency spi-matching" configured. I changed it to "crypto ipsec nat-transparency udp-encapsulation", which fixed the issue. Maybe this will save somebody else some head aches.

Thanks bfoll.

i hate you for thinking of isakmper before me! ;) very clever

you da man, thank you

Thank you so much for putting the time and work into this site and your lessons.

I'm very interested in using Xbee with an Arduino for a project I have in mind. And your videos give more depth of information than any I've found. Kudos!

Your Xbee S2 Quick Reference Guide not only keeps all of the needed info at your fingertips, but the logical arrangement makes everything easier to understand.

I'll be making a small donation to help to continue this great work.

Hey man, I did not initially recognize your news design, the old one was better )
Thank you for the website, it helps me to study the VPN steps. I am CCNP in routing and switching and studding the how is VPN working
