This problem has been bothering me for a long time. The same issue occurs when the bike light device network is set up and data is transmitted/received in SimulANT+. Is there any configuration for NRF54 or NRF52 that can be referred to? 2026-01-06T08:04:24+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/8066/ https://www.thisisant.com/forum/viewthreadANT/viewthread/8066/#When:00:18:05Z I've been trying to implement the ANT+ Bike Light profile. At present I'm trying to get the shard master/slave channel to work properly.<br /> <br /> I've been seeing these Page 247 and Page 243 packets showing up from those devices as part of the Bike Light Profile. I see them in the simulator when also connected to a Garmin device as well as in my logs in my own code. Sometimes I get a Page 70 requesting it.<br /> <br /> I can't find any mention of those pages either in the ANT+ Bike Light document or the Common Pages document. Is there any information about those pages?<br /> <br /> Thank You 2025-01-31T00:18:05+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7715/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7715/#When:03:30:59Z We want to develop a bicycle light that supports ANT+, using nRF52832 as the main control, and S332 as the protocol stack we use.<br /> There is no related demo about ANT+ bicycle lights in the ANT+ demo provided by Nordic. We want to get the relevant Profile. 2024-02-28T03:30:59+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7704/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7704/#When:13:46:25Z Hello,<br /> <br /> Developing a smart light, we realize that the Garmin Edge is sending an OFF order during the first 5 minutes of the activity to every connected lights.<br /> This order is send by the computer on his own, with no user interaction.<br /> <br /> We saw this with Garmin Edge 830 and 840.<br /> Lights used are under development Syncros lights and also Garmin Varia lights.<br /> This is not happening 100% of the time.<br /> <br /> Did you already experienced this, and do you plan a correction on this?<br /> <br /> Kind regards,<br /> <br /> LEMAIRE Martin<br /> <br /> 2024-01-19T13:46:25+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7685/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7685/#When:13:45:17Z Hello, <br /> <br /> During field tests, we realize that the behavior of Edge 840 in Network auto mode with our lights is very different from the behavior with the Edge 830.<br /> <br /> Is it an issue of our light or is there an update regarding this on the Edge 840?<br /> <br /> Thank you for your reply,<br /> <br /> Kind regards,<br /> <br /> LEMAIRE Martin 2023-09-25T13:45:17+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7639/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7639/#When:22:25:50Z Hi,<br /> I connected to the Magene L508 bike radar and its light from nRF52840 dongle. I tried to cycle through the light standard modes. Somehow the mode I set and the mode that light reported do not match. Not sure if my understanding of the ant light specification is incorrect or the light manufacturer did it their way.<br /> <br /> The light page 02 says: 02 01 16 07 44 F0 00 04<br /> My understanding is: it supports high/low beam, supports 5 modes and from standard modes it supports mode 4, 5, 6 and 7.<br /> <br /> When I sent page 34 to set the standard modes from 4 to 7 the lights reported:<br /> Set Mode 4<br /> The light reported page 01: 01 01 4A 00 79 FF 08 2D - current mode 2<br /> Set Mode 5<br /> The light reported page 01: 01 01 4A 00 7B FF 14 0A - current mode 5<br /> Set Mode 6<br /> The light reported page 01: 01 01 4A 00 7C FF 18 28 - current mode 6<br /> Set Mode 7<br /> The light reported page 01: 01 01 4A 00 7D FF 20 23 - current mode 8<br /> <br /> I checked if I read the page 01 bytes 5 and 6 specification correctly multiple times. Still do not understand how from modes 4, 5, 6 and 7 I got 2, 5, 6 and 8.<br /> <br /> Do the tables 7-7, 7-12 and 7-43 from the ant light specification talk about the same modes? Or the page 34 has some other modes indexing?<br /> Is missing bit 0 description in the table 7-7 important?<br /> <br /> Thanks,<br /> Rado<br /> <br /> 2023-02-22T22:25:50+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7620/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7620/#When:14:13:19Z Hello,<br /> <br /> When in Individual network mode, and selecting Auto Mode for a specific light, we see the attached communication. (AutoModeEntrance.png)<br /> <br /> First question is , why sending periodically the command 0x0E (Medium)?<br /> Second is what is the 0xF3 meaning?<br /> <br /> When trying to go in another mode, Off for example, we have the second attached communication: (AutoModeExit.png)<br /> <br /> So it seems that when entering Individual Auto mode, it is impossible to exit it. Is it correct?<br /> If not can the light can do something about it?<br /> <br /> The only solution to exit it I found is to go to auto network mode and back to individual.<br /> <br /> Kind regards,<br /> <br /> Martin 2022-11-04T14:13:19+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7610/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7610/#When:07:12:09Z Hello, <br /> <br /> We are facing an issue with Network option set to Auto mode and a Garmin Edge 530.<br /> <br /> When changing mode (or event switching off the light) using the button on the light itself. This does not "override" the network option to individual. <br /> <br /> We realize that doing the same on a VARIA RTL510, it was overriding the model the network mode to individual in the Garmin Edge 530.<br /> So we are wondering what is the trigger to switch Garmin Edge 530 Network mode.<br /> <br /> Thank you in advance for your help,<br /> <br /> Martin 2022-09-30T07:12:09+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7579/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7579/#When:06:58:30Z Are there any SIMULANT+ versions that support bike light device and controllor profile? <br /> If not, are there any plans or versions that will be released? 2022-02-22T06:58:30+00:00 https://www.thisisant.com/forum/viewthreadANT/viewthread/7511/ https://www.thisisant.com/forum/viewthreadANT/viewthread/7511/#When:04:24:13Z Hi Great support teams: <br /> <br /> We've developed Bike light for a while. So far, we'd like to make bike light as a secondary light in system.<br /> But we could not catch messages from controller through shared channel. <br /> <br /> Here is the environment of our experiment : <br /> <br /> 1. We use host MCU (STM) with nrf24ap2-8ch as ANT radio to build up.<br /> 2. We use a bike light (Bonntrager) as main light in system.<br /> 3. We use Edge-530 as bike light controller.<br /> 4. Here are the commands we send for setting device as secondary light: <br /> <br /> A4 09 4F 21 02 DD E5 58 7B 4F 06 B5 <br /> //received connect command from bike controller<br /> <br /> A4 03 42 01 00 00 E4 = A4 03 40 01 42 00 A4 <br /> // command for assign channel [shared slave channel(1)] = responses from nRF24ap2 <br /> <br /> A4 05 51 01 01 00 24 06 D2 = A4 03 40 01 51 00 B7<br /> //command for set channel ID [shared slave channel(1)] = responses from nRF24ap2 <br /> <br /> A4 03 43 01 F4 0F 1E = A4 03 40 01 43 00 A5<br /> //command for set channel period [shared slave channel(1)] = responses from nRF24ap2 <br /> <br /> A4 02 45 01 39 DB = A4 03 40 01 45 00 A3<br /> //command for set channel frequency [shared slave channel(1)] = responses from nRF24ap2 <br /> <br /> A4 01 4B 01 EF = A4 03 40 01 4B 00 AD<br /> //command for open channel [shared slave channel(1)] = responses from nRF24ap2 <br /> <br /> A4 09 4E 01 02 01 40 00 E5 FF 00 FF 44<br /> //command for sending Data Page 1 – Light States 1 in shared channel<br /> <br /> <br /> After the last command we send above, we never received any command from shared channel.<br /> <br /> (Bike controller could see our device and our device could joined the network as a secondary bike light.) <br /> <br /> <br /> 5. Attachment is the log file (.fit) we recorded from bike light controller (Edge530), it about the whole process of how we connect main light / secondary light and try to set properties of secondary light. <br /> <br /> If there is any other info you need to know, please notice me, thanks!<br /> <br /> <br /> <br /> Sincerely <br /> <br /> EISO-Jack<br /> <br /> 2021-04-28T04:24:13+00:00
