  1. Hi there, I´m testing radio range with two new CC1350 Launchpad Rev. 1.1 on Windows 7 64bits. When I try with SmartRF Studio V2.6.0 with 625 bps, Legacy Long Range mode the communication has good range. I transmit with a 12 dBm and I receive 12 dBm in the other Launchpad at 1 meter between both ( on my desk). When I do the similar test with Energia EasyLink Tx - Rx example, I changed to " myLink.begin(EasyLink_Phy_625bpsLrm); ", I received a poor signal (rxPacket.rssi = -70) with the same Launchpad at the same distance. I´ve tried to save smartrf_settings.c and .h from SmartRf Studio to my Energia path, but I haven't notice any difference. My Energia path is: C:\energia_1_6_10E18\libraries\EasyLink-master\src\smartrf_settings\CC1350_LAUNCHXL Somebody knows how to improve range with Energia as same as SmartRF Studio ? Thank´s in advance. Litos97
  2. Hi there, I was looking for at this forum about how can I increase the transmit power on Launchpad C1350 to 14 dBm, but I didn't find any complete solution. I read about de ccfg.c file, I edited that file and deleted comment in red line (see below): Path: C:\Users\litos97\AppData\Local\Energia15\packages\energia\hardware\cc13xx\4.9.0\system\source\ti\devices\cc13x0\startup_files //##################################### // Force VDDR high setting (Higher output power but also higher power consumption) //##################################### #ifndef CCFG_FORCE_VDDR_HH //#define CCFG_FORCE_VDDR_HH 0x0 // Use default VDDR trim #define CCFG_FORCE_VDDR_HH 0x1 // Force VDDR voltage to the factory HH setting (FCFG1..VDDR_TRIM_HH) #endif Now in my sketch I change the power to 14 dBm: // begin defaults to EasyLink_Phy_50kbps2gfsk myLink.begin(EasyLink_Phy_625bpsLrm); EasyLink_setRfPwr(14); delay(1000); After that I check the power: #ifdef DEBUG Serial.println(myLink.version()); Serial.print ("Potencia TX (dBm) : "); Serial.println(EasyLink_getRfPwr()); #endif But nothing change, I always is 12 dBm. If I decrease the power to 10 dBm for example, getRFPwr() shows the correct information 10 dBm. Can you help with this, please ?? Thank´s in advance. Litos97
  3. Does anyone have any code examples, experience, or can point me to the right direction when it comes to reading/writing to the internal flash that comes with these boards in Energia? I'm wanting to store up to a maximum of a days worth of non-volatile 3x32 bit 5 minute samples (3,456 bytes), before sending as packets when the Rx is in range. Thanks in advance!
  4. Sleep Modes with cc1310 / cc1350

    First, I'd like to say thanks for the implementation of EasyLink for the cc1310/cc1350 in Energia 18. Last year the community was invaluable in helping me develop some MSP430FR5949/BME280 dataloggers for my dissertation research. I'm working on a new version based off the cc1310, because well, transmitting my data wirelessly sure beats having to recover the dataloggers. I have a couple questions that I have been unable to answer - 1. The EMT documentation suggests that if you use delay, during compiling this is converted to a low power mode. Is this only for the MSP430/432 variants? The main reason I ask is because sleep(), sleepSeconds(), etc... do not appear to be available for the cc1310/cc1350. Low power modes would be essential for this project. 2. As general advice, any opinions if I would be better off using Sensor Controller Studio, TI-RTOS, CCS for the development of this project and then simplify and port functionality back to Energia? As always, thanks for the help and insight.
  5. CC1350 LaunchPad

    Just spotted the CC1350 Launchpad although some of the documentation is marked April so maybe it was just me that missed it. It's a dual mode Sub-1GHz and BLE wireless launchpad. The US version seems to be available now, but the EU version is not yet available. I assume this means that it's not switchable between the US (915MHz) and EU (868MHz) band for the Sub-1Ghz bit. http://www.ti.com/tool/launchxl-cc1350
