Sorry I replied with a different account.

@Roalnd-Baldin the module is registered to the CDP (AT+CGATT = 1 and AT+CSQ = 23), this is not the problem. The problem is the registration to the Huawei part of the CDP.

With UDP we disable the auto connect to Huawei platform because of the energy consumption (AT+QREGSWT=0). For Neul Messaging this connection needs to be set up first. But this is not working. Correct me if i’m wrong.

Can someone provide me more information and AT commands for Neul messaging?

@afzal_m I registered the device as CoAP with the command you provided. This seems to go wright. When I try to send with AT+NMGS I receive an error and that error seems to come because my module is not registered on the Huawei platform. I disabled this because Huawei registration was not needed with UDP. I tried to reregister and read out the registration process with AT+NMSTATUS but the outcome is ‘Registration Failed’. Without registration on the Huawei platform AT+NMGS can’t be used. Do get me wrong, Huawei registration is not establishing a connection with the CDP.

@afzal_m can you delete my message above? I realised my IMEI number is now public

Thank you.

@afzal_m

Can you provide me the ‘adaptationLayerName’?

“additionalParams”: {
“adaptationLayerName”:“{{adaptationLayerName}}”

I tried to register the device as CoAP but got an error:

“msg”: “Incorrect Adaptation layer name for IMEI:deleted by admin device”,
“code”: 6030

@afzal_m

Thanks for your response!

I tried with quotation marks and without but no luck. Do I have to register the device as CoAP for Neul Messaging? Because the device is still registered as UDP.

Hi Afzal,

I have tried your AT-commands. Unfortunately I keep receiving CME Error 4 (operation not supported). We uploaded the newest firmware on the BC95 this week. Looks like a problem with the module. Is Neul messaging actually working on the T-mobile CDP? Because I read some topics on the forum where people keep receiving error codes. Are there more people using Neul Messaging that you know? Is DTLS supported with Neul Messaging?

Hi Afzal, Thank you! So is looks a lot like UDP only the DGRAM and NSOST are different? Do you have to be registered to Huawei platform to use Neul Messaging? Because we disabled this. Else the module will reconnect every hour if you don’t send in between.

@Roalnd-Baldin is the BC95 already supported for CoAP? I’m trying to get the BC95 from Quectel working with the new CoAP AT commands but the CDP isn’t responding.
