Can anyone suggest a GSM board that will allow me to connect my uno board to a cellular network in the US and support the use of SSL for making https requests? I have looked at several boards, but all seem to be discontinued or don't support ssl connectivity. Thanks
Arduino MKR NB 1500 with a suitable SIM card?
(assuming that by GSM you don't mean the obsolete 2G technology)
look here: Arduino SIM — Arduino Online Shop
Any idea how to connect the 1500 to a uno board?
why would you need a UNO for? the 1500 is way more powerful than your UNO
I have a system running on a uno board that I need to talk to with my mkr nb 1500
I purchased a mkr nb 1500 and have started prototyping. I have found that I can't connect to a webserver via ssl. Port 80 is fine, but 443 with the nbsslclient doesn't work. Even the sample sketches don't work. I did some research and found some folks saying the board has old firmware and it just doesn't work right. There were suggestions that this is a known issue that for some reason is not being addressed. Any suggestions?
I've seen discussions as such Firmware upgrade for UBLOX SARA-R410M-02B on the MKR NB 1500 #2 - #12 by zbelding (worth a read)
how old is your board?
are you sure it's not a certificate issue?
if this is a firmware issue then you would need to ask Arduino's support dept.
If you contact Arduino support it is important that you provide the current firmware version on your board. Depending on the version you have there are different sets of instructions so I would suggest you check before by doing the following: https://support.arduino.cc/hc/en-us/articles/360016119159-How-to-check-the-firmware-version-the-SARA-radio-module-u-blox-on-the-MKR-NB-1500
The board was purchased a couple days ago. I don't know how to determine how old it is. I am not sure how to determine if it is a certificate issue, but I tried several websites, including all the examples and all gave the same errors.
I just checked the firmware version and this is what I got:
AT+CGMR
L0.0.00.00.05.06 [Feb 03 2018 13:00:41]
OK
How do I contact arduino support. I found the help center but not seeing any way to contact support.
Just found the contact us form and submitted a request for help. Thanks to everyone for your assistance.

This indeed is an issue
Just an FYI for everyone. I worked with the Arduino tech support team to get my firmware updated and then I tested the ssl web client and it still did not work. I was then told by the support team that "at the moment, only SaraSerial Passthrough, Test Modem, and Choose Radio Access Technology are working fine for this firmware". Sounds to me like this just isn't ready yet. Not sure why they are advertising that it supports ssl when that doesn't appear to be the case.
