Hello everybody, I’m using SL6087 with firmware R7.46 (previously R7.45) and I’m facing two problems : Single AT command returns “ERROR” on uart2 although it works fine on uart1. Other AT commands work fine on both uarts. Really strange. Huge problem indicator ? SIM VCC does not work. I tried to …

Hi, Can you please specify which particular AT command returns “ERROR” on UART2 (but other AT cmd work fine on both)? Can you check product technical specification of SL6087 Section 4.7.3? Thx.

Hi, Here are some AT sequences from uart1 & uart2. On uart1 : AT OK AT+CSQ +CSQ: 13,0 OK AT+CREG? +CREG: 0,0 OK On uart2 : AT ERROR AT+CSQ +CSQ: 13,0 OK AT+CPIN? +CPIN: READY AT+CREG? +CREG: 0,2 OK AT+COPS? +COPS: 0,2,20801 OK I don’t know if “ERROR” replying to single “AT”…

Hi, For “AT” on UART2, does it happens on first “AT” or every time you query “AT”? Can you try to send AT+CMEE=1;&W, then send “AT” again to see if any error cause? For register issue, “+COPS: 0,2,20801” means it is using carrier “Orange” in France (Bonjour :slight_smile: ) and very low signal st…

Bonjour Lotam, We finally found why we were unable to register to the network. Our internal power supply was not strong enough. Using an external power supply we could exchange data and voice call. The AT error is now our last problem. We modified our connection script which started with an expect…

Hi i’m using UART2 in SL6087 and transferring data to external MSP microcontroller but at the MSP end i’m not able to get the sending data from GSM in hex format…can you please help me to get data in MSP in HEX format.

Does this really have anything to do with the rest of the 2-year old thread :question:

Hi awneil , thanks for your reply,i’m new to this forum and recently started working on SL6087 module and presently i’m using UART2 in this module… I’m trying to send data to the External MSP through UART2 using the below mentioned code and i’m not able to receive the same data at receiving end of…

Whether you’re new or old, it should be obvious that it’s inappropriate to just stick an unrelated post on the end of a long-dead discussion. Start a new thread - with an appropriate, descriptive title - for your new question.
