bluetooth advertising data

1. A callback method is sent to the Bluetooth device when it sends write datacallback after data is written-(void) Peripheral: (cbperipheral *) Peripheral Didwritevalueforcharacteristic: (cbcharacteristic *) Characteristic error: (nullable nserror *) error Because the device on our side is a blood pressure meter, it is sent to the peripheral to start the measurement, and then the measured

{static unsigned char bt_rxdata_merge_status=bt_rxdata_merge_defaul_status;//means an IAP packet is sent by a bt_rxdata if (bt_ Rxdata_merge_status==bt_rxdata_merge_defaul_status 0x55==bt_rxdata->msgdata[2]) {//detect the length of the IAP packet First// IAP packet: Length field data contains 1 or 3 bytes, depending on the length of the payload//one-byte domain can behave in a single byte 0x02 to 0xFC (2 to 252) load length//Three bytes field

This article describes the PHP implementation of the login Sohu ads to obtain the Advertising alliance data method. Share to everyone for your reference, specific as follows: Always have an idea, every time to log in to see how much the alliance yesterday? Every day to log in and trouble, can do a summary of the function of the email? Unfortunately, the verification code around, can only think of one way.

At present, the tunnel advertising system has been upgraded to a new device system with the original 256 colors, 192 × 256 resolution, 16-bit color, and 640 × 320 resolution, in addition to significant hardware upgrades and improvements, the software has also been greatly improved. 1. The volume of downloaded data has soared, from a single frame of 48 k bytes to a current 300 K byte, increasing by 15 times

effect of the I²c sensors task, you can see that the sensor controller has been able to read all the data that is of interest.The driver code in the IO sensors task is relatively simple and interesting to see the source code.~ ~ Finished, in fact, spent a lot of time to tune the drive, the main reason is the above mentioned HDC1000 cycle read the relationship, but finally is finally done.The source code of the project can be seen on the link below.Ht
