The CoAP stack of the CoAP server is based on Californium version 1 and uses the implemenation as it has been pushed by OceanConnect from Huawei. Although this implementation is not 100% standard compliant there are ublox n211 and quectel bc95 in the market which support this floavor of CoAP I checked the AT command guide of the SIM7070G. It looks like only the standard CoAP is supported. IoT Creators will provide the standard complient CoAP stack in Q1 2021. Hope this helps. Regards, Roland

@Roalnd-Baldin Thanks for helping, but not working. AT+CSOSEND=0,22,"48656c6c6f20576f726c64" OK Sim7020 working with hex length, not with the byte, so I tried with hex format, but the message not arrived the iotcreator and Beecaptor. Can you anything idea? Thanks all!

@IoT-Arista Hi, thanks for letting us know! We moved our documentation library to docs.iotcreators.com - but I think you figured that out. I will try to figure out if we can change or remove the broken links from google search. Thank you!

Hi Eben, Quick feedback: I can use GNSS and TCP at the same time using the SIM7000E using the latest firmware, which I had to update beforehand.

I have been looking to this post: https://forum.iot.t-mobile.nl/topic/310/sim7000e-accepteert-de-genoemde-commandos-niet?_=1591271570193 I like to have it work with T-mobile NB IoT on a combination of the SparkFun SAMD21 Mini Breakout connection and the SIM7000E break out board. Is there anybody who has succeeded to do so with Arduino code? Thanks in advance for your answer.
